The Thermodynamic Analysis of GP Zones in Aged-Supersaturated Al-Cu Alloys

摘要：

Being the structural cause of hardening, Guinier Preston (GP) zones in many alloys still attract much interest. The expression of energy for GP zones in Al-Cu alloy is established by combining the essential Gibbs energy with the interfacial energy and the strain energy. Based on the equilibrium between GP zones and its surrounding matrix, the quantitative analysis on the sizes, concentrations, aging temperatures and their relationships can be predicted. The size and concentration of GP zones calculated with defined composition and aging temperature accord with the experimental results well.
