在Ａｌ－Ｍｇ－Ｌｉ合金中加入Ｍｎ，Ｚｎ和Ａｇ元素，提高了合金的时效硬化程度和拉伸强度，穿晶断裂的比例增加，塑性稍有降低。这些变化与形成Ａｌ６Ｍｎ粒子和Ａｇ，Ｚｎ在δ′粒子中富集有联系。
Addition of Mn, Zn and Ag to Al-Mg-Li alloy increases the degree of age hardening and tensile strength of the alloy, increases the proportion of transgranular fracture, and decreases the plasticity slightly. These changes are related to the formation of Al6Mn particles and the enrichment of Ag and Zn in δ ’particles.
