【Abstract】 Using the average crystal cell and atom models of the empirical electron theory of solids and molecules (EET),the effects of interstitial impurities on valence electron structures and melting point of Ti Al alloys were analyzed.Because of the effects of interstitial impurities,atoms hybridization states increase,bond structures are seriously anisotropic,and the melting points are decreased.更多还原
