摘要: 對不同合金化程度的GH151,GH37,GH33鎳基高溫合金和GH36,GH69鐵基高溫合金,采用固溶后緩冷工藝或固溶后等溫工藝處理,結果表明:均可形成彎曲晶界。同時發現形成彎晶的機制不僅與熱處理工藝有關,并與合金成份有關。Abstract: Two kinds of heat-treatment method are used for Ni-base superalloys GHl51,GH37,GH33,and Fe-base supsralloys GH36 and GH69.The results show that the Zig-Zag grain boundaries are formed in air these alloys. It has been found that the mechanism of Zig-Zag G. 33. formation is dependent not only on heat-treatment method but on compositions of alloys.
