The compressive proof stress of the polycrystalline TiAl wasfound to be a positive temperature dependence as same as the single crystal one.The correlation of the flow stress together with strain rate and deformation tem-perature is in good agreement with the expression: ε=Aσ_p~nexp(-Q/RT)Adjusting the deformation temperature and strain rate to a decrease in flow stressof alloy down to below its brittle fracture stress may improve successfully notonly the hot working of the TiAl-base alloy but also the fineness of the recry-stalline grains.
