鉴于我国许多变形高温合金(如GH33、GH37、GH49、GH698和GH220等)是引进或类同苏联高温合金体系以及这些合金仍广泛地用于现役航空发动机关键部位的转子零件(如盘和叶片)的客观事实,经常注意苏联在变形高温合金技术条件方面的动向是很有必要的。现摘录两则简讯,这无疑将对国内在判断和处理有关变形高温合金生产交货和验收使用过程中的某些争执起一定的参考作用。 In view of the fact that many of our deformed superalloys such as GH33, GH37, GH49, GH698 and GH220 are introduced or similar to the Soviet superalloy system and these alloys are still widely used in the rotor parts (such as disks and blades) of key parts of active aviation engines, The objective facts, often pay attention to the Soviet Union in the deformation of superalloys technical aspects of the trend is necessary. Now extract two newsletters, which will undoubtedly play a certain reference role in judging and handling some of the disputes in the production, delivery, acceptance and use of deformation superalloys.
