摘要
介绍了国内外高温合金特别是单晶高温合金材料开发和制备方法的研究现状,综述了精密铸造高温合金在航空发动机、地面燃机、火箭发动机、舰船和车辆等军用和民用领域的应用及需求情况。指出高温合金的研发事关国家安全与国计民生。
An introduction was made to the status of development and preparation of materials for superalloys, especially single crystal superalloys, at home and abroad. The applications of precisely casted superalloys in civil and military fields such as aero-engines, gas turbine engines, rocket engines, ships and vehicles were overviewed as well as the demands for the superalloys. It is pointed out that the development of superalloys concerns both the national security and the national welfare and people's livelihood.
