摘要
利用光学显微镜观察3003铝合金铸轧板、冷轧板以及冷轧板退火后的显微组织,用电子拉伸试验机进行拉伸试验,获得不同退火温度下铝板的力学性能,讨论了退火温度对该合金显微组织、抗拉强度和伸长率的影响。结果表明,随退火温度升高,抗拉强度下降,达一定温度后趋于稳定,伸长率的变化规律则相反;从而确定3003合金的再结晶温度为460℃。
The microstmcture of continuous casted plate ,cold rolled sheet and annealed sheet of 3003 aluminium alloy were observed by photo-electro metallographical machine, the mechanical properties were obtained through mechanical property test. The effects of annealing temperature on microstructure, tensile strength and elongation were discussed. The results show that the tensile strength decreases with the increase of annealing temperature, then tends to a fixed value. The change rule of elongation is opposite. The perfect recrystallization temperature is 460℃,
