針對月球環境溫度變化情形，研究了長時間低溫浸泡(?196 ℃)和多次高低溫交變循環處理(?196~200 ℃)對擠壓態AZ31鎂合金在20 ℃下的力學性能、顯微組織以及斷口形貌的影響。研究表明：AZ31鎂合金經過長時間液氮浸泡和高低溫交變循環處理后，力學性能無明顯變化；室溫態合金的σb和δ分別為288 MPa和18.3%，經過10 d低溫浸泡后σb和δ分別為292 MPa和18.7%，經過10次高低溫循環后合金的σb和δ分別為294 MPa和16.9%；低溫和高低溫交變處理對斷口形貌和相組成沒有明顯影響，均為準解理斷裂。
In view of the lunar environment temperature change situation, the influence of long time low temperature immersion (?196 ℃) and high-low temperature alternation processing (?196?200 ℃) on the mechanical properties, microstructures and fracture surfaces of AZ31 magnesium alloy at 20 ℃ was studied. The results indicate that there are no significant changes on the mechanical properties of AZ31 magnesium alloy after liquid nitrogen immersion or temperature alternation cycle treatment. The σb?and δ of AZ31 magnesium alloy at room temperature are 288 MPa and 18.3%, respectively, after 10 d cryogenic processing, they will reach 292 MPa and 18.7%, respectively. σb?and δ after 10 times high-low temperature alternation processing are 294 MPa and 16.9%, individually. SEM observation and XRD results show that the fracture surface and phase constitutions do not change obviously after low temperature or high-low temperature alternation processing. And the fractures are both quasi-cleavage crack.
