The microstructure variation during heat treatment and the correlation between structure and room temperature tensile properties of TiAl based alloy were studied.The duplex structure,composed of fine lamellar colonies and equiaxial γ grains,with superior room temperature plasticity can be obtained by heat treatment at γ+α phase zone with controlled cooling rate.It is believed that its plasticity results from fine grains and higher volume fraction of lamellar structure.
