ABSTRACT The nickel-based superalloys Hastelloy X and Haynes 214 are widely used for honeycomb liners; however, thermo-physical properties at temperatures close to the melting range are poorly described in the literature. Based on the thermo-physical properties, endothermic effects between 550°C and 650°C have been observed that develop due to the formation of the short-range order in both alloys and in Haynes 214, in addition to the short-range order, an increase in the specific heat capacity due to the γ′-precipitation up to 950° was detected. At low and intermediate temperatures, the Hastelloy X is significantly better suited than the Haynes 214. At high temperatures the Haynes 214 is superior to the Hastelloy X due to the dissolution of the γ′-phase.

Hastelloy X 和 Haynes 214 接近熔点范围的热物理性能

摘要 镍基高温合金 Hastelloy X 和 Haynes 214 广泛用于蜂窝衬里；然而，在接近熔程的温度下的热物理性质在文献中的描述很少。根据热物理性质，除了短程有序之外，由于在两种合金和海恩斯 214 中形成了短程有序，已经观察到 550°C 和 650°C 之间的吸热效应，由于 γ'-沉淀高达 950°，检测到比热容增加。在低温和中温下，Hastelloy X 明显优于 Haynes 214。在高温下，由于 γ' 相的溶解，Haynes 214 优于 Hastelloy X。
