Hysteresis, Avalanches and Interfaces in Solid Phase Transformations

Hysteresis, Avalanches and Interfaces in Solid Phase Transformations

L3, Mathematical Institute, Andrew Wiles Building, Oxford

In recent years there has been significant progress in the experimental and theoretical understanding of solid phase transformations, as exemplified by the recent systematic search for and discovery of ultra-low hysteresis alloys that can be thermally cycled millions of times with negligible damage. In these materials and others,  the transformation involves interfaces between the high temperature austenite phase and complex microstructures of the low temperature martensitic phase. The formation of such microstructures is accompanied by avalanches of acoustic emissions. Compatibility of the parent and product phases is both a crucial element in understanding these phenomena, and leads to deep unsolved mathematical questions.

The objective of the conference is to further advance the constructive interplay between theory and experiment on these topics, bringing together both leading experts and early career researchers.
