摘要
第二代粉末高温合金FGH96是采用损伤容限设计思想研制的新型粉末高温合金,是当前750℃工作条件下满足高推比、高燃效发动机使用要求的涡轮盘、环形件和其他热端部件的理想材料。结合FGH96惯性摩擦焊接头的组织特征和强化相γ′数量分析接头的显微硬度和常温拉伸性能。结果表明,FGH96惯性摩擦焊接头具有良好的常温力学性能。
The secondary P/M powder superalloy FGH96 is the late-model superalloy designed by the method of damage of tolerance limit.FGH96 is the most perfect material of turbine disk,loop-forming element and other components assembly of hot end to meet the challenge of high thrust-weight ratio and high efficiency aircraft engine in 750℃.Combined with grain feature and volume fraction of γ′of FGH96 IFW joint,microhardness and normal tensile property was discussed.The results show that IFW joint exhibits well mechanic...
