目前对γ′相含量高的弥散强化镍基合金的热机械强化展开一系列工作。研究结果表明对这些合金进行热机械处理(TMO)(包括在(γ+γ′)区域塑性变形和在γ′-相完全固溶温度以下的热处理相结合)是很有效的。本文着重研究了用于航空发动机圆 At present, a series of work is carried out on the thermomechanical strengthening of dispersion strengthened nickel-based alloys with high γ ’phase content. The results of the study indicate that it is very effective to thermomechanically treat these alloys (TMO), including plastic deformation in the (γ + γ ’) region and heat treatment below the complete solution temperature of the γ’-phase. This article focuses on the aero-engine circle
