摘要
The microstructure of the Ti-5Al-4Sn-2Zr-1Mo-0.25Si-1Nd (Ti-55) alloy containing second phase particles was studied. The second phase particles are 1 similar to 15 mu m in size and most of them are distributed at the grain boundaries in the form of ellipsoid with a few short needle-like and blocky phases. It consists of either dark or bright amorphous 'matrix', and some small spots dispersed within the 'matrix', which match SnO (orthorhombic, a=0.500 nm, b=0.572 nm, c=1.12 nm).
