Calculation of Valence Electron Structure of Precipitate Phases in Al-Cu Cast Alloy

Abstract:

Article Preview

Based on Empirical Electron Theory in solid (EET) and Bond Length Difference (BLD) the valence electron structures of precipitates in AlCu alloy during aging process were calculated. The results show that the different phase structure factors explain the thermal stability of phases in θ sequence, and the tendency of atoms solution is corresponding with the phase transition during aging from valence electron structure levels, which reveals the inside causes of ageing hardening is closely related to the covalent electron pairs in some bond of the precipitations and matrix.
