superalloy; diffusion bonding; hot isostatic pressing 1 Introduction CuAgZn alloy consisting of copper, silver and zinc is a Cu-based alloy, which has the features of low melting point, good fluidity and wettability. GH909 superalloy is a new kind of Fe-Ni-Co based superalloy with low thermal expansion, high strength and plasticity, high thermal fatigue resistance, low expansion coefficient......
加Re新型单晶高温合金熔体与Al2O3型壳界面状况研究 张勇1,马书伟1,曹腊梅1,张德堂1,曾强1 (1.北京航空材料研究院,) 摘要:对加入Re的新型单晶高温合金与Al2O3型壳之间的界面状况进行了研究.结果表明,在1550℃下,熔融的合金液体不会与Al2O3型壳产生反应,Al2O3型壳是与DD3+2Re(wt%)新一代单晶配合良好的材料. 关键词:高温合金; 型壳; 界面; [全文内容正在添加中] ......
in superalloy 1(with a composition of γ- 9.8wt%(Ti + Al)), which can deteriorate its castability. The type and morphology of the eutectics changed and the amount considerably decreased with decreasing Ti + Al content in superalloy 2(with a composition of γ- 7.6wt%(Ti + Al), 1.5wt% Nb). Thus, it is predicted that the castability would improve for superalloy 2. The same trend was observed for superalloy......
