摘　　要：通过微观组织分析、力学性能检测和断口形貌分析,研究了铝合金气瓶的二次时效对其微观组织和力学性能的影响。研究发现,二次时效后,铝合金的析出相更细小弥散均匀,其屈服强度和抗拉强度都会有所提升。Through the microstructure analysis,mechanical properties detection and fracture morphology analysis,the influence of the secondary aging of aluminum alloy gas cylinder on its microstructure and mechanical properties was studied.It is found that after the secondary aging,the precipitation phase of aluminum alloy is even smaller and uniform,and its yield strength and tensile strength are improved.
