“…It is shown that the slow cooling rate (50-80°C/min) and overaging at 560°C/2 h significantly reduced the yield stress and the ultimate tensile strength, and tensile elongations of CuCrZr SCA relative to CuCrZr SAA. Previous studies have found that cooling rates >1200°C/min are required to fully quench the Cu-Cr solid solution [28][29][30]. The relatively slow cooling rate in the CuCrZr SCA treatment resulted in a lower nucleation rate (due to reduced Cr supersaturation levels) and more rapid precipitate coarsening compared to the optimum CuCrZr SAA treatment.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
