摘　　要：本文叙述了GH36合金锻件低倍试验面应力腐蚀——热应力扩展混合裂纹的特征、形成及扩展机制。为锻件低倍试验中防止误判提供重要依据。This paper introduces the characteristic .form and spread mechanism of stress corrosion and heat stress spreading combined crack on macroetching test surface of GH36 alloy forgings. This provides the importance basis for protecting from erroneous judgement in macroetching test of forgings.

关 键 词：应力腐蚀 裂纹 低倍试验 锻件 高温合金
