摘要

PROBLEM TO BE SOLVED: To provide: a Co-Ni based alloy in which a crystal is easily controlled; a method of controlling a crystal of a Co-Ni based alloy; a method of producing a Co-Ni based alloy; and a Co-Ni based alloy having controlled crystallinity.SOLUTION: The Co-Ni based alloy includes Co, Ni, Cr, and Mo, wherein the Co-Ni-based alloy has a crystal texture in which a Goss orientation is a main orientation. The Co-Ni based alloy preferably has a composition including, by mass: 28 to 42% of Co; 10 to 27% of Cr; 3 to 12% of Mo; 15 to 40% of Ni; 0.1 to 1% of Ti; 1.5% or less of Mn; 0.1 to 26% of Fe; 0.1% or less of C, and an inevitable impurity; and at least one selected from the group consisting of 3% or less of Nb, 5% or less of W, 0.5% or less of Al, 0.1% or less of Zr, and 0.01% or less of B.
