1. study the discipline that the composition and content of modifier have influences on the microstructure and mechanical properties at RT(room temperature) of Al-Cu alloy in order to optimize the best content and composition of the modifier and reveal its mechanism of interaction. 2. study the discipline that the best composition of modifier and different heatly-treating process affect the dynamic conditions of formation and growth(shape,size,quantity,distribution)of nano-sized nuclear precipitated, growth . Reveal the discipline of kinetics and conditions having impacts on formation and growth of nano-sized nuclear. 3. study the mechanical activity(at RT)of the best modifier under different strain rate and reveal the mechanism of alloy's deformation behavior(at RT) under different mechanical strain rate. |
