【Abstract】 Investigations are made of the IF of martensitic transformation in a CuZnAl alloy quenched from high temperature. The new expression of the IF is put forward: It is considered that the IF of martensitic transformation is also concerned with the ratio of the modulus of the whole (G)to that of the localized regions where the martensitic transformation is taking place (G’) and the quenched defects would affect the localized modulus soft. And the effects of incomplete transformation on martensitic and reverse transformation has been studied.更多还原
