My research area is mainly about using computational methods to simulate the recrystallization behaviour of aluminium alloys during deformation and annealing. The study on recrystallization is vital for industry as the grain size, grain shape and texture can be controlled during hot rolling and solution heat treatment process of commercial Al alloys, while refining the grain size is the only way to improve the toughness of alloys in the meanwhile of improving strength. Therefore, providing reliable computational models that can predict the recrystallization process are significant for scientific engineers to optimize the microstructure and obtain specific material properties of alloys.

 In my PhD project, a phase field model coupled with a finite element method will be applied to study the microstructure evolution during recrystallization, based on the theory of the minimization of stored free energy. The model will be validated by the experimental results on Al alloys at the final stage. The overall aim of this project is to provide a trustable and stable model for the engineering industry to make massive production of Al alloys used in aircraft construction.
