Strategic Partnership in Structural Metallic Systems for Gas Turbines
Lead Research Organisation:
University of Cambridge
Department Name: Materials Science & Metallurgy
Abstract
The UK aerospace industry is the largest in Europe and, worldwide, second only to the US. The aerospace sector directly
supports more than 3,000 companies and provides 230,000 jobs in the UK. Importantly, most of this employment falls
outside the south-east and the average wage is above the national average. In the UK, the manufacture of gas turbine
engines represents 32% of the aerospace business and is dominated by Rolls-Royce, with 114,000 jobs supported by
Rolls-Royce and its supply chain.
This research programme brings together the universities of Birmingham, Cambridge, Imperial College, Manchester,
Oxford, Sheffield and Swansea, to perform the fundamental research required to realise new materials technologies that
will provide step-changes in the efficiency of gas turbines. This will help secure the commercial competitiveness of much of
the UK aerospace industry whilst simultaneously serving to reduce UK CO2 emissions, thereby satisfying international
legislation and decreasing the likelihood of irreversible climate change.
The research will focus on the development of the new, high performance steels, nickel, cobalt, titanium and niobium-based
alloys required for the most demanding applications with gas turbine engines. It will also seek to obtain the
fundamental understanding of the performance and degradation of these materials needed to ensure that they may be
used safely, without compromising engine performance. It will also include additional activities investigating key enabling
technologies, such as advanced joining methods and materials for turbine blade seals.
These materials technologies will be developed in close collaboration with the industrial partners to ensure that they are
matched to industrial need and that a route for commercial exploitation is available.

Planned Impact
This programme seeks to develop the innovative materials technologies and supply the trained staff required to maintain
commercial competitiveness of the UK's gas turbine industry. The beneficiaries will be:
UK industry
* This programme involves the universities of Birmingham, Cambridge, Imperial College, Manchester, Oxford, Sheffield
and Swansea, bringing together their expertise to develop the new materials required for the future health of the UK gas
turbine industry.
* The research staff and related postgraduate students will provide the next generation of trained metallurgical scientists
and engineers required to meet the recruitment needs of UK industry.
UK society
* The Strategic Partnership will develop the materials technologies required to maintain the commercial competitiveness of
the UK's largest aerospace company and thereby secure the UK jobs in this vibrant manufacturing sector. Rolls-Royce and
its supply chain support 114,000 UK jobs and the whole UK gas turbine industry supports some half a million UK jobs.
* The development of gas turbines with increased efficiency will help the UK cope with dwindling natural resources, meet
its commitments to EU emissions targets and limit potential damage through dangerous climate change. The potential
impact is considerable as around 7% of the UK's CO2 emissions are associated with gas turbines in international aviation,
while approximately 16% of the UK's CO2 emissions are associated with power generation using gas turbines of various
descriptions.
UK public
* A broad multimedia portfolio of professionally delivered public engagement activities will ensure effective dissemination
to million-scale audiences across the UK. This will include podcasts, local, regional and national radio contributions, live
interactive events for the general public, web articles and outreach activities for schools. By virtue of our multimedia
approach, these initiatives will also access audiences traditionally judged hard-to-reach and younger demographics
representing the researchers of tomorrow.
* Increased awareness of the excitement and importance of physical metallurgy as a scientific discipline will inspire the
next generation of metallurgists and engineers.
UK policy makers
* The benefits of carefully managed academic research in underpinning the future prosperity of UK manufacturing will be
communicated to UK policy makers.
* The partners will support RCUK efforts to fund industry/academia collaborations through press releases, articles and
case studies highlighting the impact achieved through this programme.

| Description | The objectives of the Strategic Partnership in Structural Metallic Systems for Gas Turbines were to: 1. To undertake the fundamental materials research necessary to improve the efficiency and environmental sustainability of gas turbine engines. 2. To train the next generation of world-class materials scientists and metallurgical engineers in structural metallic systems that will be critical to the future health of the discipline in UK academia and industry. These objectives were met through collaborative research and training activities run between academia and industry. This fully utilised the capabilities of a wide section of the academic community to develop new materials technologies that will give improvements in the performance of gas turbines, as well as performing the fundamental science required to ensure that they are safely used to the limits of their capabilities. This research was performed under the guidance and support of the industrial partners who will ultimately use these materials technologies, thereby providing intrinsic pathways to commercial exploitation. Key successes from the Strategic Partnership include: • A new niobium silicide alloy has been designed, which could provide a step change in turbine blade operating temperature. A company has been engaged to fabricate this alloy using commercial routes for detailed testing. • New polycrystalline nickel-based superalloys for turbine disc applications, capable of operating at higher temperatures and stresses than existing alloys, have been developed and are now in the process of industrial scale-up and assessment. These will provide a key cornerstone for future gas turbine aero engines. • The relationships between the dwell crack growth behaviour, which limits the service life of turbine disc components, and alloy microstructure have been established for both current state-of-the-art and next generation disc alloys. This will allow the latest alloys to be processed for optimal dwell fatigue resistance. • Developed and applied specialist capabilities for observation of microstructural changes in alloys during mechanical testing using in situ scanning electron microscopy. These have been used to gain a fundamental understanding of strain localisation around microstructural features during deformation. • Established a new method for studying TCP phase formation in superalloys in situ using synchrotron X-ray diffraction. • Developed an understanding of the fatigue crack growth threshold behaviour of polycrystalline nickel-based superalloys associated with the friction welds that are used to create the turbine assemblies. This offers the prospect of more appropriate component lifing, with commensurate savings through reduced service costs. • Established an understanding of the interactions between processing parameters, microstructure and the resultant properties on aerospace alloys produced using additive manufacturing methods. • Validated a new surface hardening treatment for aircraft engine bearing steels involving nitriding plus carburising that increases surface hardness well beyond that achieved with carburising alone. • Developed and demonstrated a new creep-resistant, tough and strong shaft material based upon a precipitation strengthened maraging steel containing NiAl and Laves phase intermetallics. This new steel provides a single-material solution for the aircraft engine shaft that removes the need to inertia weld different materials for a balance in front and rear mechanical properties. This is now being assessed in commercial quantities. • New insights have been obtained in the deformation mechanisms of titanium aluminides that will facilitate future alloy processing and component lifing. The realisation of such technologies will help maintain the commercial competitiveness of the UK gas turbine industry, helping secure a very significant number of jobs within UK manufacturing, as well as the possibility of further job creation. The Strategic Partnership has received national recognition, winning the 'Collaborate to Innovate' award in the Transport category in 2016 and the IOM3 Gold Medal in 2018. |

| Title | HRDIC dataset of strain localization in shot peened Ni superalloy |
| Description | We used high-resolution digital image correlation (HRDIC) to measure strain distribution at each deformation step near the shot peened surface of a Ni superalloy, deformed in tension at 450 C. To make the DIC analysis possible, we first developed a fine, homogeneous distributed gold speckle pattern by remodelling a thin gold layer previously deposited on the polished sample surface. The gold layer was deposited using an Edwards S150B sputter coater for 4 minutes providing a ~40-45 nm thickness gold layer. Then, the sample was placed in the heating plate of the remodelling device for 6 hours at 300 °C. During the remodelling process, water vapour flows onto the surface of the coated material and remodels the gold layer into fine speckles. In order to avoid any possible speckle coarsening during the high temperature tensile testing, the remodelled sample was heated in a furnace at 475 °C for 5 hours and air cooled to stabilise the gold pattern. Due to the required stabilization heat treatment, the average speckle size was 120 nm, which is coarser than in previous studies at room temperature, where no pattern thermal stabilization is needed. We used a FEI Magellan HR 400L FE-SEM with a theoretical resolution of = 0.9 nm at <1kV to take backscattered electron images of the pattern. The images were obtained at a working distance of 3.5 mm, 5 kV and 0.8 nA beam current. Mosaics of 30x15 images were used to cover 950x420 squared microns, an area shown area in Fig. 1). Each image contains 2048 x 1768 pixels and has a horizontal field of view of 43 microns. The images were overlapped by 20% to enable easy stitching prior to the digital image correlation. We obtained 7 mosaics, one before tensile testing and 6 after each deformation step. The mosaics for the un-deformed and deformed state were correlated using LaVision's digital image correlation (DIC) software (version DaVis 8.3). The correlation was performed using a sub-window size of 1616 pixels and no overlap, which provides a spatial resolution of about 335 nm. This resolution allowed us to handle the large data sets generated when covering such large areas (each mosaic was 45.5k x 20k pixels in size). The correlation produces full-field in-plane displacement maps u(x1, x2, 0) on the plane x1x2 with normal x3. Code for reading and visualizing this data is available here: https://doi.org/10.5281/zenodo.4727939. The shear strain data is also provided as a python dictionary saved as a NumPy array. Visualization previews are given as .png and .gif files. |

| Title | Observation of a new B2 structured phase in Ti-15Mo (wt%) |
| Description | © 2018 The Authors The formation of non-equilibrium and transient phases in metastable beta titanium alloys during low temperature thermal treatments is currently of great interest, as they provide a potential method of controlling the size and distribution of the equilibrium alpha phase and, hence, the resulting mechanical properties. Here, for the first time, we report on the formation of a new, B2 structured phase in the Ti-Mo system. The phase was observed in electron transparent material during in situ, and following ex situ, heat treatment at 300 °C. The B2 phase was enriched in Mo compared to the surrounding matrix material and formed in regular arrays of approximately square cross-section particles interspersed by thin beta channels. Electron diffraction indicated that the lattice parameter of this new phase was smaller than that of the parent phase, leading to significant strain in the beta channels. Critically, the B2 phase was only observed in material that had been electro-polished prior to heat treatment, and, therefore, it is hypothesised that this phase forms as a result of the preparation method and thin foil effects. |

| Title | RAW SEM images mosaics dataset for the HRDIC strain localization study in shot peened Ni superalloy |
| Description | We used a FEI Magellan HR 400L FE-SEM with a theoretical resolution of = 0.9 nm at <1kV and = 0.8 nm at = 5kV to take backscattered electron images of the fine, homogeneous distributed gold speckle pattern obtained by remodelling of a thin gold layer previously deposited on the polished sample surface. The images were obtained at a working distance of 3.5 mm, 5 kV and 0.8 nA beam current. Mosaics of 30x15 images were used to cover 950x420 µm2. Each image contains 2048 x 1768 pixels and has a horizontal field of view of 43 µm. The images were overlapped by 20% to enable easy stitching prior to the digital image correlation. We obtained 7 mosaics, one before tensile testing and 6 after each deformation step.
