摘要
综述了 Ti Al基合金中扩散型α→γL 析出转变和非扩散型α→γm 块状转变的研究新进展 ,着重阐述了α2 /γ片层组织的晶体学特征、形成机理和γm 相的形核。
An investigation on the mechanism of phase transformation in the TiAl based alloy is very important for us to establish the relationship between microstructures and mechanical properties. The recent advances in the research of diffusional α→γ\-L precipitate transformation and non diffusional α→γ\-mmassive transformation are reviewed. The crystallographic feature and formation mechanism of α\-2/γ lamellar microstructure, and the nucleation, growth and ordering mechanisms of massive transformed γ m phase are discussed in detail.
