| description | The present work describes the development of a novel in-situ synchrotron diffraction technique for the characterisation of the microstructure evolution which occurs during IFW. These studies have quantified, for the first time, the spatial and temporal evolution of phase fractions which is produced by this process.
The technique has been applied for a steel and a nickel-based superalloy, assessing the evolution of microstructure which occurs for these materials. Furthermore, relationships between micro-scale evolution and macro-scale behaviour have been investigated to assess whether the microstuctural changes which occur control the mechanical evolution of the process.
A novel Cellular Automata approach has been developed to analyse whether thermally-driven phase transformations represent the experimental results produced. |
