The effects of Mn adding on solution structure and tensile properties of ultra-high strength aluminum alloy were studied by OM, SEM and XRD analysis.
通过光镜、扫描电镜和X射线衍射的观察以及力学性能检测，研究了在高强铝合金中加入锰后对合金固溶组织和拉伸性能的影响。
Under the high-temperature conditions, all the samples fracture in the side of aluminum; with the rise of temperature, tensile strength of the joint declines obviously, while elongation increases;
高温条件下，试样均断于铝端母材，抗拉强度随着温度的升高呈现出明显的下降趋势，而伸长率随温度升高而增大；
