“…Ni600 and Ni625 are austenitic solidsolution alloys, primarily comprising three precipitated phases: titanium nitrides, titanium carbides, and chromium carbides. Despite the varying concentrations of niobium, titanium, aluminum, and other elements in these alloys, the primary types of carbides are largely confined to MC, M 6 C, M 7 C 3 , and M 23 C 6 (where M represents the metal elements) [1,5,6]. Ni625 predominantly contains MC, M 6 C, and M 23 C 6 , while Ni600 contains M 7 C 3 and M 23 C 6 [7][8][9][10][11].…”
