铝合金的淬火与一般结构钢的淬火意义不同.单一用淬火工序不能使铝合金达到强化的目的.刚刚淬火的铝合金,强度提高很少很少.但铝合金常常采用淬火工艺,其主要意义在于两个方面:一是使它的塑性提高有利于拉伸矫直等精整工作;二是为时效强化作准备工序.淬火加热时将强化相充分溶解,在高速冷却后得到均匀过饱和固溶体,
Aluminum alloy quenching and general structural steel quenching meaning is different.Unique quenching process can not make the aluminum alloy to achieve the purpose of strengthening.After just quenching the aluminum alloy, the strength is rarely increased.However, the aluminum alloy is often used quenching process, its main significance Lies in two aspects: one is to make it plasticity is conducive to stretching straightening and finishing work; the second is for the preparation of aging strengthening process.Quenching heating will be fully dissolved phase, after high-speed cooling to obtain a uniform supersaturated solid solution ,
