Description | It is emphasised that work is not yet complete but significant results have been obtained and published. Rolling contact results in sub-surface stresses that are repeated on each occasion that a wheel traverses a rail surface. As a result damage accumulates, leading eventually to failure. We have published the mechanism of this failure in a carbide-free bainitic rail and demonstrated that it is totally different from that assumed conventionally for rails and bearings. The results have generic value since carbide-free bainitic steels have wider applications than rails. Considerable more work has been done in collaboration with ArcelorMittal with a further publication. |
Exploitation Route | Both the publications and data are available on the web, and the work has stimulated a different line of thought in the context of bearing steels. That has been highlighted to bearing steel manufacturers, mainly via publications. Wilberth Solano, who was the post-doctoral research assistant, is now employed by ArcelorMittal to continue the work for exploitation, and over the last year there is a contract with the University of Cambridge for him to spend three months per annum to use our characterisation facilities. |

Title | Research data supporting "Soft novel form of white-etching matter and ductile failure of carbide-free bainitic steels under rolling contact stresses |
Description | The data form the basis of a publication, entitled "Soft novel form of white-etching matter and ductile failure of carbide-free bainitic steels under rolling contact stresses", Acta Materialia, 121 (2016) 215-226. The files are self-explanatory, with images, experimental data including microscopy, microanalysis, X-ray diffraction, SIMS, crystallographic analysis. The folders are labelled appropriately. https://www.repository.cam.ac.uk/handle/1810/260341 |
