Integrated Modelling and Analysis of Multiple Component Carbides in Welded hardfacings
Welded hardfacings are functional layers applied to the surface of steel components to improve the wear and/or corrosion resistance with typical applications in civil engineering, mining, agriculture, recycling and maritime industries with a huge market. The structure of the hypereutectic Fe–Cr–C hardfacing alloy consists of a large quantity of primary carbides ‘M7C3’ (where M could be Fe, Cr, i.e. (Fe, Cr)7C3) or other solution elements replacing Cr or Fe) within an eutectic matrix (Austenite+finer carbides). A particular technical research focus of the project is on investigating factors controlling the crystal/lattice structure and properties of the carbides and on developing approaches for combined performance improvement and structure refinement through integrated physical based predictive simulation and analysis. The R&D involves development in theories, new materials, data-led research tools and systematic data which is essential for the materials design and process optimisation. The interdisciplinary research is built on previous establishments from the team and project partners to advance the scientific understanding and development of an important material group based on advanced physical based modelling. The theories, advanced tool, new materials and data are transferable to other areas of materials and processing developments. Improvement of the structure and properties (either the primary carbides or the matrix) of the hardfacing to increase its wear resistance has a significant economic and social impact given its wide applications (e.g. efficient use of metal resources, competitiveness of industries and use of advanced technologies). Apart from the technical research and development, the project will continue to contribute to the global effort in applying data science in materials and processing innovation through data-driven and data-informed technologies. The proposed project aims to investigate the crystal/lattice structure and properties of carbides in welded hardfacings and the mechanisms and technologies for carbide strengthening and refinement. One area is to investigate the effects of different solution elements including RE elements on the crystalline/lattice structure and properties of primary carbides using the first principle calculations; Another area is to develop materials with refined structures integrating ab initio evolutionary algorithm techniques and physical modelling. The project covers interdisciplinary work to develop new knowledge, technology development through research, training/knowledge exchange and collaboration.

Project objective
The proposed project aims to investigate the crystal/lattice structure and properties of multi-component carbides M7C3, and the mechanisms of carbide refinement in welded hardfacing process through integrated physical based predictive simulation and analysis. The main objectives: 1. To investigate the effects of different solution elements including RE elements on the crystalline/lattice structure and properties of primary M7C3 carbides using the first principle calculation. 2. To develop a new approach to predict the stable chemical compounds formed during the welding process of Fe-Cr-C hardfacings using ab initio evolutionary algorithm techniques and big data system; 3. To develop a new software and interface program tocomputerise the lattice misfit calculation in order to predict the probability of a compound formed in the welding process to act as the heterogeneous nucleus of primary M7C3 carbides and establish the carbide refinement mechanism. 4. To provide training on specific physical based predictive simulation and advanced analysis by the host and the project partner. This application is based on a novel approach to identify the chemical structure and properties of one most widely used carbides in the welding repair and maintenance process, leading to the development of a practical physical based simulation tool with potential scientific, industrial, economic and environmental impact in both the EU and worldwide. This programmeoffers an opportunity to cement collaboration between international award winning multidisciplinary research in the Host and partner organisations (Scientific Computing Department of the Science and Technology Facilities Council, several EU Universities and companies). If supported, this Individual Fellowship (IF) will significantly accelerate the development of the research skills and career of the ER, and will open up new areas of research and new external collaborations for the host with academics and industrial partners.
