以测量物理和力学性能变化的方法,研究不同冷拔变形度对阿尔德莱依型铝合金时效过程中固溶体分解各階段的影响。结果指出冷拔变形显著加速时效过程的进行,并由计算出的α固溶体分解时的扩散激活能,推辞时效过程中抗张程度最高值受硅原子扩散所控制Q=25400卡/克原子,而电导率反应速最快时间受镁原子的扩散所控制Q=38000卡/克原子。 In order to measure the change of physical and mechanical properties, the effect of different cold-drawn deformation on the decomposition of Al-Lai-Lay aluminum alloy during the aging process of solid solution. The results show that the cold drawing deformation accelerates the aging process significantly, and the maximum value of the tensile strength during the decay aging process is controlled by the diffusion of silicon atoms, Q = 25,400 cal / g atom, from the calculated diffusion activation energy of α solid solution. The fastest time of conductivity reaction is controlled by the diffusion of magnesium atoms Q = 38000 calories / gram atom.
