一、前言 粉末冶金技术的发展为机械制造工业开辟了极其广阔的前景。自七十年代以来各先进的工业国家为适应航空工业发展需要、面对能源和原材料价格上涨的形势,均很重视发展粉末冶金及快速凝固的新工艺和新技术。特别是美国在F100发动机上成功地采用了粉末冶金高温合金涡轮盘和压气机盘后,一批高推重比的加力涡扇发动机(如美国的F100、F101、F401、F404及英、西德、意大利的RB199等)都分别采用粉末高温合金制的盘件及其他零件,使发动机实现了“大推
First, the preface The development of powder metallurgy technology has opened up a very broad prospect for the machinery manufacturing industry. Since the 1970s, all advanced industrial nations have adopted new technologies and new technologies for the development of powder metallurgy and rapid solidification in order to meet the needs of the aviation industry. In the face of the rising prices of energy and raw materials, In particular, the United States succeeded in using the powder metallurgy superalloy turbine disk and the compressor disk on the F100 engine. A group of afterburner turbofan engines with high thrust-to-weight ratios (such as F100, F101, F401, F404, , Italy, RB199, etc.) are used powder made of high temperature alloy plate and other parts, the engine to achieve a "push
