摘　　要：2618铝合金压气叶轮力学性能要求非常高,在模锻热处理后坯料无法满足要求。通过增加自由镦粗工序,增加了变形量,细化了晶粒,最终满足了验收要求。The requirement of mechanical property of 2618 aluminium alloy impeller is very high. After the die forging and heat treating, the billet can not meet the requirement. Through adding the upsetting procedure, the deformation degree was increased, the grain size was decreased. Finally it met the acceptance requirement.

关 键 词：2618铝合金 变形程度 固溶时效
