摘要:

采用OM, SEM, TEM和EPMA, 对Ti和Al含量不同的Fe-Ni基合金在900-1030 ℃固溶温度范围内的η相析出行为进行了研究. 结果表明, η相的形成与合金中的Ti含量和Al含量密切相关, 提高(Ti+Al)含量或Ti/Al比, 可增加η相的析出倾向; 在980 ℃固溶处理后, 低(Ti+Al)含量和Ti/Al比的合金中不存在η相, 而在高(Ti+Al)含量和Ti/Al比的合金中仍存在η相; 随合金(Ti+Al)含量或Ti/Al比的增加, γ'相可在更高温度存在, 在高温固溶处理过程中, η相消耗合金中的 $\gamma'$ 而析出并长大; 合适的固溶温度可消除合金中的元素偏析和抑制η相的析出.

关键词 ： Fe-Ni基合金, η相, 固溶处理, 析出行为

Abstract：

Fe-Ni base austenitic alloys have been widely used as structural materials in the hydrogen environment, which is strengthened by the precipitation of γ' [Ni₃(Al, Ti)]. η phase is present after solution treatment in some modified alloys, which is detrimental to hydrogen resistance performance of alloys. In order to eliminate the $\eta$ phase and optimize the alloy composition, the precipitation behavior of η phase in Fe-Ni base alloys with different Ti and Al contents was investigated in the range of 900 ℃ to 1030 ℃ using OM, SEM, TEM and EPMA. The results show that the formation ability of η phase is related to the content of Ti and Al. Increasing the (Ti+Al) content or the Ti/Al ratio in the alloys promotes the precipitation of η phase. Moreover, the η phase does not exist in alloys with the lower (Ti +Al) content or Ti/Al ratio, but still presents in the alloys with higher (Ti+Al) content and Ti/Al ratio after the standard solution treatment at 980 ℃, which is due to that the η phase precipitates at the expense of the γ' phase existing at higher temperature. In situ microstructure observations indicate that η phase and elemental segregation can be eliminated by the optimization of solution treatment condition.

Key words： Fe-Ni base alloy η phase solution treatment precipitation behavior
