摘要
The morphologies of the Nd-rich phase particles in the Ti-5Al-4Sn-2Zn -1Mo-0.25Si-1Nd alloy after high temperature deformation are investigaied by optical microscope and transmission electron microscope. It is found that the Nd-rich phase particles are 1.0～14 μm in diameter and uniformly distributed in ihe matrix, and the majority of the particles are elliptical. Under high temperature deformaiton, high stress concentration occurs on the particles, the particles near to sphericity are obtained.
