英文摘要The microstructure and mechanical properties of Ti-22Al-24Nb-0.5Mo electron beam weld was investigated. The FZ (fusion zone) is composed of fully collunar B2 grains in the FZ center and the dentritic B2 grains on top and bottom of the weld. Their distribution is symmetrical to the fusion line center. Two post-weld annealing schedules, namely 850 degrees C/2 h/AC (aged) and 980 degrees C/2 h+850 degrees C/24 h/AC (solution treat+aged, STA), have been carried out. The STA weld exhibits a coarser O phase than the aged weld in the FZ and the alpha(2) phase reappears. The tensile strength at room temperature of the welds for these two annealing conditions are similar, while the aged weld is a little stronger at high temperature. The creep rupture life of the STA weld is higher, and the fracture mode is intergranular for both aged and STA welds.
