Notes:
Microstructure and texture evolution during equal channel angular pressing (ECAP) ofAl-5 mass%Ti alloy are investigated for up to 8 passes via routes A and BC. Platelet-shaped Al3Tiparticles in the Al-5mass%Ti alloy are cracked severely with repetitive ECAP passes, and the meansize of the Al3Ti particles is decreased with increasing the number of ECAP passes.Microstructural observation showed that an Al–Ti supersaturated solid solution is formed during theECAP process. It is also found that the Al-Ti alloy after ECAP by route A and route Bc methodshave very different microstructures. Namely, after ECAP by route Bc, the fine Al3Ti particles arehomogeneously dispersed in Al matrix, while the microstructure has highly anisotropic distributionafter ECAP by route A
