摘要

研究了 GH141 变形高温合金的冷加工硬化特性、静态再结晶及热处理对合金硬度、组织的影响。结果表明，GH141 合金固溶温度须在 1060℃温度以上，在 1060℃保温 4min 硬度才出现较显著下降；冷却速度对硬度影响显著，水冷软化效果明显好于空冷；1000℃以上退火，冷却速度的影响超过了热处理温度的影响，说明冷却过程中析出硬化掩盖了热处理软化效果；γ′大幅度回溶需 1050℃以上；冷变形后的合金在 1050℃即能完成再结晶，1120℃以上会发生晶粒长大。

Abstract

In this paper

the cold work hardening characteristics

static recrystallization characteristics and the effect of heat treatment on the hardness and microstructure of GH141 nickel-based deformation superalloy had been studied. The results show that the solution temperature of GH141 alloy must be above 1060℃. The cooling speed has a significant effect on the hardness

and the effect of water-cooling softening is obviously better than air cooling

which shows that precipitation hardening covers the softening effect of heat treatment during cooling. It needs to be heated above 1050℃for γ′ large-scale dissolution. The recrystallization of the cold deformed alloy can be completed at 1050℃

and the grain coarsening will occur above 1120℃.
