摘要
概述了欧美国家粉末高温合金热挤压工艺的发展历程与应用情况,阐述了我国粉末高温合金热挤压工艺的研究进展,介绍了René 95、René 88DT和FGH4096合金的挤压工艺参数选取原则,重点分析了挤压工艺参数(挤压比、挤压速度、挤压温度等)对粉末高温合金挤压成形及组织性能的影响规律,阐明了热挤压过程中粉末高温合金非金属夹杂物的演变行为.
Abstract
The development and application of hot extrusion process for P/M superalloys in Europe and US were summarized.The research progress of hot extrusion process for P/M superalloys in China was described.The selec-tion principles of extrusion process parameters for Rene 95,Rene 88DT and FGH4096 alloys were introduced.The influence of extrusion process parameters(extrusion ratio,extrusion speed,extrusion temperature,etc.)on the ex-trusion forming,microstructure and properties of P/M superalloys was emphatically expounded.The evolution be-havior of non-metallic inclusions in P/M superalloys during hot extrusion was clarified.
