The deformation compatibility and recrystallisation behaviour of the alloy CuSn10P1

This paper performs a comparative analysis between as-cast and semi-solid CuSn10P1 in state of hot compression deformation. Compared to original billets, the brittle phases intergranular microstructures are reduced, while tangled dislocations occur inside β’-Cu13.7Sn phase, generating slipping bands twins. The precipitation reduction phase smaller difference Young's modulus matrix contribute improvement deformation compatibility among grains, as well smooth surface with no cracks. Combined results misorientation, Euler's angle rotation, grain boundary distribution, dynamic recrystallisation mechanism billet is dominated by discontinuous grain-boundary bulging nucleation. continuous sub-grain rotation plays major role billet. As true strain increases, accumulate at boundary, rearrangement merging through dislocation or climbing. These findings provide theoretical guidance for hot-compression CuSn10P1.
