实验选用Al-Mg-Si-Cu铝合金板材为实验材料,对其时效工艺进行了研究。结果表明:第二次时效温度较低时,短时一次时效可获得较高的强度。
The experiment selected Al-Mg-Si-Cu aluminum alloy plate as the experimental material, the aging process was studied. The results show that when the second aging temperature is low, the higher strength can be obtained by short time aging.
