摘　　要：研究了水温对该合金模锻件淬火应力场的影响,分别计算了水温15℃、25℃和35℃时的淬火应力场。结果表明:淬火水温不同时,该模锻件的淬火应力场均呈环状分布;随淬火水温的升高,淬火终冷时间缩短,淬火应力的最高值降低;较优的淬火水温应为35℃。The influences of water temperature on quenching stress fields of Al alloy drop-forged were studied.The quenching stress fields at 15 ℃,25 ℃ and 35 ℃ were calculated.The results indicate that the quenching stress fields in quenching 7075 aluminum alloy drop-forged is symmetrical ring distribution at different temperature.The time of final quenching and the biggest quenching stress value decreases with the increase of water temperature,and the better water temperature in quenching is 35 ℃.
