冶金工业部于1979年下达了“高温合金中微量元素的控制及其作用”课题的研究任务,参加研究工作的各单位经过近七年的共同努力,全面、如期地完成了计划研究内容,取得了显著成果。 研究涉及的合金包括GH220、GH698、GH169、GH99、GH33A、GH37、GH36、GH132、GH135、GH302、GH901及GH761等18种高温合金,涉及的微量元素包括Mg、Zr、Ca、B、Ce、La、Hf、Y、Pb、Te、Sn、As、N、H、C、Si等16个元素,对于Mg在变形高温合金中的作用及含量控制进行了系统和深入的研究。 In 1979, the Ministry of Metallurgical Industry issued the research task of “Control and Function of Trace Elements in Superalloys”. After nearly seven years of joint efforts, all units participating in the research completed the planned research contents comprehensively and on schedule, Significant results. The alloys involved in this study include 18 superalloys such as GH220, GH698, GH169, GH99, GH33A, GH37, GH36, GH132, GH135, GH302, GH901 and GH761. The trace elements involved include Mg, Zr, Ca, B, Ce and La 16 elements such as Hf, Y, Pb, Te, Sn, As, N, H, C and Si have been systematically and deeply studied on the role and content control of Mg in the deformed superalloy.
