目前在国外较先进的航空发动机和民用燃气轮机上,燃烧部件大多采用性能较高的镍基合金868和Hastelloy X来制造。这些合金用大量的钨钼元素固溶强化,使合金保持高塑性和优良的抗氧化性的同时,大大地提高了热强性,同时也具有良好的冲压、焊接等工艺性能,因而在高温燃烧部件上得到了广泛的应用,如Hastelloy X合金是目前美国喷气发动机生产中用量最大的高温合金之一。
Currently in the more advanced foreign aircraft engines and civilian gas turbines, most of the combustion components using high performance Ni-based alloy 868 and Hastelloy X to manufacture. These alloys with a large number of tungsten and molybdenum solid solution strengthening, the alloy to maintain high ductility and excellent oxidation resistance at the same time, greatly improving the thermal strength, but also has good stamping, welding and other process performance, and thus at high temperature combustion Parts have been widely used, such as Hastelloy X alloy is currently the largest US jet engine production of high temperature alloys.
