Abstract

In this paper, an isothermal diagram of the second phase formation in the Hastelloy G35 alloy was constructed to understand possible phase transformations during welding. A welded joint has been studied in three areas: fusion zone (FZ), the heat affected zone (HAZ), and the base metal (BM). The FZ is represented by a dendritic structure; in addition, σ-phase intermetallic compounds are present in the FZ and HAZ. Furthermore, the FZ and BM present similar hardness values, while the hardness increases in the HAZ. It has been established that thermal effects for different areas are characterized by different rates of increase up to 650°C.

用于熔盐作业的耐腐蚀镍合金焊接接头的结构与性能

本文构建了哈氏合金 G35 中第二相形成的等温图，以了解焊接过程中可能发生的相变。研究了焊接接头的三个区域：熔合区 (FZ)、热影响区 (HAZ) 和母材 (BM)。熔合区呈树枝状结构；此外，熔合区和热影响区还存在 σ 相金属间化合物。此外，FZ 和 BM 的硬度值相似，而 HAZ 的硬度则有所增加。已经确定，不同区域的热效应具有不同的特征，在高达 650°C 的温度下，热效应的增加率也不同。
