综述了镍基高温合金的化学、物理和机械特性，重点介绍了该类材料在涡轮机发动机中的应用。讨论了主要和次要合金添加剂在多组分商业铸造和锻造高温合金中的作用。显微组织的稳定性和阶段观察过程中，并在随后的高温服务进行了总结。处理路径和处理的最新进展。机械性能和变形机制进行了审查，包括拉伸性能，蠕变，疲劳和循环裂纹扩展。
The chemical, physical, and mechanical characteristics of nickel-based superalloys are reviewed with emphasis on the use of this class of materials within turbine engines. The role of major and minor alloying additions in multicomponent commercial cast and wrought superalloys is discussed. Microstructural stability and phases observed during processing and in subsequent elevated-temperature service are summarized. Processing paths and recent advances in processing are addressed. Mechanical properties and deformation mechanisms are reviewed, including tensile properties, creep, fatigue, and cyclic crack growth.
