05Cr17Ni4Cu4Nb二次受热温度对力学性能的影响

Effect of Secondary Heating Temperature on Mechanical Properties of 05Cr17Ni4Cu4Nb

主要研究了材料05Cr17Ni4Cu4Nb二次受热后对汽轮机动叶片本体性能的影响。试验结果表明,材料05Cr17Ni4Cu4Nb二次受热温度不超过时效温度610℃或Ac 1点670℃时,力学性能及金相组织均不会发生变化。

The influence of secondary heating for the material 05Cr17Ni4Cu4Nb on the performance of steam turbine blades has been studied.The results show that when the secondary heating temperature of 05Cr17Ni4Cu4Nb is less than aging temperature 610℃or 670℃at Ac 1 point,the mechanical properties and microstructure of the material will not change.
