【摘要】：對GW63K鎂合金進(jìn)行不同工藝的T6熱處理。結(jié)果表明:固溶處理不但可以提高合金的強(qiáng)度,還能使其保持良好的塑性,而時(shí)效處理能使T4態(tài)GW63K合金的強(qiáng)度進(jìn)一步提高,但會(huì)降低其伸長率。隨著T61、T62、T63和T64四種熱處理中固溶溫度從545℃降低到525℃,GW63K鎂合金的強(qiáng)度基本不變,而伸長率得到提高;固溶溫度繼續(xù)從525℃降低到515℃,GW63K鎂合金的強(qiáng)度開始下降,而伸長率繼續(xù)提高。對比后發(fā)現(xiàn),T63態(tài)合金的力學(xué)性能完全滿足技術(shù)指標(biāo)要求,為最佳熱處理工藝。
[Abstract]:T6 heat treatment of GW63K magnesium alloy was carried out by different processes. The results show that solid solution treatment can not only improve the strength of the alloy, but also maintain good plasticity, while aging treatment can further improve the strength of T4-state GW63K alloy, but reduce its elongation. With the decrease of solution temperature from 545 鈩，
