Abstract

A bimodal grain structure Ti–22Al–25Nb alloy with enhanced ductility is fabricated from the blended powder mixture of argon gas atomized powder and mechanically alloyed powder by spark plasma sintering. The microstructure of the bimodal grain structure Ti–22Al–25Nb alloy and the effects of the argon gas atomized powder mass fraction on the compression properties are investigated. This alloy shows the bimodal microstructure, which the coarse grain regions are surrounded by the ultrafine grained matrix. Compared with the Ti–22Al–25Nb alloy sintered from 100% mechanically alloyed powder, this alloy sintered from the blended powder mixture containing 20% argon gas atomized powder exhibits the fracture elongation to improve 20.5%.
