Abstract
This study investigated the effect of degree of ordering in Alloy 600 steam generator (SG) tube material on the initiation of primary water stress corrosion cracking (PWSCC), using a slow strain rate test (SSRT). The material was cooled in air from 1,100^oC to 550^oC, and below 550^oC the cooling rate..... More

Abstract
It has been proposed that a primary water stress corrosion cracking (PWSCC) in pressurized water reactor (PWR) is governed by a lattice contraction due to a short range ordering reaction in Alloy 600. This leads researcher to think that the kinetics of lattice contraction may control a susceptibility of PWSCC..... More
