Abstract

PURPOSE: To improve strength, toughness and stress corrosion crack resisting property of an alloy in pure water under high temperature and pressure by means of a specified heat treatment in the manufacture for Ni base alloy containing Cr and Nb etc.
CONSTITUTION: An Ni austenite alloy containing 0.01W0.15% C, less than 2% Si, less than 2% Mn, 15W25% Cr, 1W5% Mo, 0.1W2% Al, 0.1W2% Ti, 2W7% Nb less than 0.01% B and residual Ni is used for structual members in a nuclear reactor. The ingot of the Ni alloy is primarily homogenized at 1,130W1,200°C and formed by hot plastic working with reduction of area more than 30%. Since then, said alloy is aged at 600W760°C, after the solution heat treatment has been achieved at 920W1,080°C. Consequently, Laves phase composed of intermetallic compounds between metals containing Ni mainly and Nb, is removed, and austenite structure including fine precipitated particles, is obtained. Thus, Ni alloy with high strength, toughness and stress corrosion crack resisting property in pure water, may be used for manufacturing parts of a nuclear reactor.
