摘要：
Asymmetric rolling (ASR) can introduce larger shear strains than symmetric rolling (SR). Therefore, application of ASR to metal-based multiphase alloy containing platelet particles will yield different particle distributions compared with SR. In this study, differences in the fragmentation behavior of Al3Ti platelet particles in Al–Al3Ti multiphase alloy after SR or ASR were investigated in three dimensions. The size of the Al3Ti platelet particles in the ASR-treated multiphase alloy was smaller than that in the SR-treated multiphase alloy. The platelet shape of the Al3Ti particles in the multiphase alloy deformed by rolling was retained because deformation by rolling occurs via plane strain. The results show that both SR and ASR can be used to modify the distribution of Al3Ti platelet particles in Al–Al3Ti multiphase alloy, but that ASR can change it more severely.
