GH220合金中γ′强化相
Gamma Prime Strengthening Phase in Superalloy GH220
-
摘要: 研究了GH220化学成分及含量,γ′析出倾向性及晶体结构、错配度、合金元素对γ′量的影响以及γ′的形态、尺寸、长大规律。Abstract: The chemical composition and content of superalloy GH220, precipitation tendency ofγ’ and crystal structure, -misfit of gamma prime are studied. The effect of alloying elements on the content of gamma prime,on the growth rule and the change of its shape and size are researched.
