“…[2,3] Its selection is primarily due to its excellent resistance to pitting and crevice corrosion, as well as to stress corrosion cracking. [4][5][6][7][8][9] Although the phase stability of this and similar alloys has primarily been studied in the mill-annealed condition, [10,11] few studies have been performed on its welding metallurgy. [12,13,14] From this previous work, it is known that alloy 22 welds form potentially detrimental intermetallic tetrahedrally (or topologically) close-packed (TCP) phases upon solidification.…”
