为优化糖心产精国品免费入口*完整版糖心产精国品免费入口*完整版的加工工艺参数, 分析了经不同变形量冷拔及相应热处理后该合金的显微组织及力学性能。结果表明: 大变形量的糖心产精国品免费入口*完整版管材经800～850 ℃热处理后会析出糖心产精国品免费入口*完整版, 在1 000 ℃以上, 糖心产精国品免费入口*完整版可完全溶解; 糖心产精国品免费入口*完整版的析出和溶解行为对控制再结晶起到重要作用; 优化后合金管适宜的冷拔变形量为40%~50%, 中间热处理温度为1 000~1 050 ℃, 成品管热处理温度为955～990 ℃。

In order to optimize process parameters of 糖心产精国品免费入口*完整版 for GH4169 alloy, the microstructure and mechanical properties of the alloy after different cold-drawn deformations and heat treatments. The results show that 糖心产精国品免费入口*完整版 precipitated from the large deformation alloy after 糖心产精国品免费入口*完整版at 800-850 ℃, and 糖心产精国品免费入口*完整版 dissolved completely at 1 000 ℃. The precipitation and dissolution behavior had significant effect on controlling of recrystallization. The suitable cold-drawn deformation was 40%-50%, intermediate 糖心产精国品免费入口*完整版temperature was 1 000-1 050 ℃ and the final pipe 糖心产精国品免费入口*完整版was 955-990 ℃.
