研究了均匀化热处理时保温后的冷却速度对ＧＨ１４１合金热塑性的影响·研究结果表明，冷却方式显著影响均匀化热处理效果·保温后缓冷过程中析出大尺寸、方形γ′粒子，超过了位错与γ′粒子交互作用方式的临界尺寸，合金变形时位错以Ｏｒｏｗａｎ机制绕过γ′粒子，从而使合金变形抗力降低，热塑性提高·
The effect of cooling rate after heat preservation on the thermoplasticity of GH141 alloy was studied. The results show that the cooling method significantly affects the effect of homogenization heat treatment. After annealing, the large-size and square γ ’ The critical dimension of the interaction with γ ’particles is that the dislocations of the alloy are bypassed with γ particles by the Orowan mechanism so that the deformation resistance of the alloy is reduced and the thermoplastic property is improved.
