Abstract: sing the Average Lattice and Atom Modelsofthe Empirical Electron Theory of SolidsandMolecules( EET), the effects of interstitial impurities on valence electron structures and melting pointof Ti- Alalloysareanalyzed .Becauseoftheeffectsofinterstitialimpurities,atoms hybridization statesincrease, bondstructuresareseriously anisotropic,andthe melting pointsare decreased .

Key words: Ti- Alalloys, melting points, valenceelectronstructure, interstitialim purities
