摘要	The influences of alloying elements W; Mo, Cr, and Nb on retained beta phase in 47Al based near gamma-TiAl alloys have been studied. The results reveal that the amount of retained beta phase is increased by the addition of Cr, Mo, W in rising rank, although the distribution of beta phase in Cr-bearing alloys is different from that of Mo- or W-bearing alloys. For Nb-doped alloys, no retained beta was found even when 5 at. pct Nb was added. The as-cast microstructural features and the distribution of the beta phase in the different alloy families were compared and interpreted in terms of the different segregation behaviour of these elements in Ti.; The influences of alloying elements W; Mo, Cr, and Nb on retained beta phase in 47Al based near gamma-TiAl alloys have been studied.
