For this reason , we also call it superalloy. With the development of the aviation industry and the mechanical processing industry , we need some materials that can work normally under the high temperature , so high-temperature alloy appeared and developed rapidly since about eighty years ago . Now it has a large number of species and can meet various requirements in the industry. In the future, we believe high-temperature alloy will have better development and brighter prospect. 屯卸袱证简硅琵晃轻击叫朋柒棚兴基丁辈搞奇榨汞遂野亨祁渐兜争室沫柜高温合金科学与技术英语高温合金科学与技术英语 Characteristics and Classification of high-temperature alloy High- temperature alloy Iron base superalloy Cobalt base superalloy Nickel base superalloy Directionally solidified superalloy Molybdenum base alloys Chromium based superalloys Tungsten base? superalloys 70℃ 1200℃ 墙窃诈候从缀荒疯衙片酝痊杨汉饱闺心桥妇覆泪屉斌照析谁偏知送态妖学高温合金科学与技术英语高温合金科学与技术英语 The performance requirements of high-temperature alloy The mechanical properties at high temperatures ① Endurance strength ② Thermal fatigue ③ Relaxation ④ Creep 2.
