摘要

研究了在真空感应熔炼条件下

不同的固溶处理冷却方式对Ni-Cr-W-Co合金组织和力学性能的影响。结果表明

在试棒上涂覆1309D涂料后经非真空热处理炉1 210℃×4h+空冷

合金中γ′相较铸态时要细小

均匀性更佳

γ′相含量达73.3%。合金经非真空热处理炉1 210℃×4h+空冷处理后

枝晶干上γ′相棱角分明、立方化效果较好

尺寸的一致性、分布的均匀性也较好

γ′相含量约为74.2%

合金力学性能较之其他处理方式更好。试样经真空1 210℃×4h+炉冷处理后γ′相粗化并成球状

力学性能变差。

Abstract

Effects of solid solution treatment with different cooling Ways on the microstructure and mechanical properties of a cast nickel-based alloy under the condition of VIM（vacuum induction melting）were investigated.The results reveal that with solid solution treatment at 1 210 ℃for 4hin non-vacuum heat treatment furnace and air cooling as well as spraying 1309 Dcoating on the bar

the size ofγ′phase in dendritie with the higher unifromity and 73.3%volume fraction is finer than that in as cast alloy.In addiiton

with solid solution at 1 210 ℃for 4hin non-vacuum heat treatment furnace

γ′phase particles in dendrite exhibits cubic morphology with distributed more uniformly

andγ′phase fraction reaches 74.2%

and mechanical properties are satisfied.With solid solution at 1 210 ℃for 4hours under vacuum condiiton

γ′phase particles are coarsened to spheroidization

deteriorating the mechanical properties of the alloy.
