前言近代航空、航天、核能、燃料转化(如煤的液化、气化、油的裂解)等工业的发展,推动了高温合金的科研与生产,而后者的进步又反过来促进了上述工业的进一步发展。以燃气轮机为例,自从开始发展以来,进气温度平均每年要提高6～9℃。工作温度的提高不仅意味着高温强度的提高,而且对合金抗高温腐蚀的性能也提出了更高的要求。不仅如此,近年来由于能源紧张,迫使
Preface The development of industries such as aviation, aerospace, nuclear energy, fuel conversion (such as coal liquefaction, gasification and oil cracking) has promoted the research and production of superalloys, and the latter progress has in turn promoted the further development of these industries development of. Taking gas turbines for example, since the beginning of development, the average temperature of the intake air has been increased by 6 to 9 ° C per year. The improvement of working temperature means not only the improvement of high temperature strength, but also the higher requirement for the performance of high temperature corrosion resistance of alloy. Not only that, in recent years due to energy constraints, forcing
