| Abstract: | Ti-45Al-8.5Nb-0.2W-0.2B-0.02Y(at%) ingot was prepared using a vacuum induction furnace,and then machined with a crusher in argon atmosphere.Subsequently,microfine spherical high Nb containing TiAl alloyed powders were obtained by fluidized bed jet milling in inert gas and then by radio frequency argon plasma.The fabrication process and characteristics of the powders were investigated.The results show that the powders fabricated by this process is highly refined and spheroidized,and the particle size is accu... |
