摘要: 对IN718合金进行二次固溶处理,研究了二次固溶处理对其组织及高温拉伸性能的影响。结果表明,经二次固溶处理后,IN718合金组织中δ相含量较一次固溶增加,高温屈服强度降低。随二次固溶温度升高,δ相析出减少,高温屈服强度升高。

Abstract: Effect of secondary solid solution treatment on microstructure and high temperature tensile property of the IN718 alloy was investigated. The results show that compared with primary solid solution treatment, the content of δ phase in the IN718 alloy increases and the high temperature yield strength decreases after the secondary solid solution treatment. With the increase of secondary solid solution treatment temperature, the δ phase precipitation decreases, the high temperature yield strength increases.

Key words: IN718 alloy, secondary solid solution treatment, microstructure, properties
