摘　　要：将经过或未经过电解充氢的铝硅合金(ZL107)试样在液氮中浸泡后,再置于空气中一定时间,其抗拉强度有不同程度的改善.液氮保存及其后的暴露使ZL107中充入的氢外逸,而且在外逸的过程中试样的部分固溶氢也随之逸出,造成试样氢含量的下降.After Al-Si alloy specimen(ZL107) hydrogened and not hydrogened by electrolyzation is immerged inlipuid nitrogen and inarir exposed for some time, the tensile strenged was improved obviously. It is thoght preliminarily that this is because heat treatment technology not only makes the hydrogen intentionally hydrogenated escaped, but also promotes the solid solution hydrogen to escape.

关 键 词：液氮浸泡 铝硅合金 电解充氢
