摘　　要：研究固溶处理温度对650~700℃超超临界汽轮机转子用改型IN706合金组织与性能的影响规律。结果表明,固溶处理温度对室温拉伸性能影响很小,但过高的固溶处理温度会使材料的700℃拉伸塑性明显下降,同时也会影响材料的冲击性能。通过观察微观组织发现,固溶处理温度的升高会使晶粒度明显长大,从而影响到材料的力学性能。The analysis of the effect of solution treatment temperature on the structure and properties of modified IN706 alloy developed for making the rotor of ultra-supercritical steam turbines reveals the temperature of solution treatment has little influence on the tensile properties at room temperature,and the extreme high temperature of solution treatment can reduce significantly the tensile plasticity and impact properties of the material at 700℃.The observation to the microstructure finds out the rise of the temperature of solution treatment can enlarge the grains of the material significantly and hence affect the mechanical properties.
