摘要	The tensile and fracture behavior of an orthorhombic alloy Ti-22Al-24Nb-0.5Mo (at%) with three types of microstructure were investigated in the temperature range between 25 degrees C and 650 degrees C. The O+bcc microstructure (basketweave lath type) possesses an elongation maximum at 500 degrees C and its drop at 650 degrees C has been attributed to dynamic strain aging as suggested by previous investigators. The alpha(2)+bcc microstructure has the highest room temperature elongation (epsilon(f) > 18%) and the cause of the elongation drop at 650 degrees C is suggested to be the fine O phase precipitates from the bcc phase. An optimal balance between strength and plasticity was achieved in the alpha(2)+O+bcc microstructure.; The tensile and fracture behavior of an orthorhombic alloy Ti-22Al-24Nb-0.5Mo (at%) with three types of microstructure were investigated in the temperature range between 25 degrees C and 650 degrees C.
