Abstract:Deep cryogenic treating (DCT) was applied on Cu-14Fe and Cu-8Cr in-situ composites and its effects on mechanical property and electrical conductivity of the composites were investigated. For comparison, the effects of DCT on properties of the corresponding composites with 0.1%Ag alloying (i.e. Cu-14Fe-0.1Ag and Cu-8Cr-0.1Ag) were also investigated. The results showed that the ultimate tensile strengths of Cu-14Fe and Cu-8Cr were greatly raised by 106MPa and 56MPa after DCT, respectively, whereas those of the C… Show more
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.
