自７０年代初开始研究低膨胀高温合金以来，已取得了很大进展，相继有十几种不同类型的低膨胀高温合金问世，并被广泛地用于航空发动机上，以缩小旋转部件和固定部件之间的间隙。研究表明，合金元素和热加工工艺对组织和性能有重要影响。
Since the beginning of the 1970s, great progress has been made in the research of low-expansion superalloys. More than a dozen different types of low-expansion superalloys have come into being and are widely used in aeroengines to reduce the size of rotating and stationary components The gap between. Studies have shown that alloying elements and hot working processes have a significant effect on the organization and properties.
