Abstract:In permanent magnets based on the Sm2Co17 phase, the high coercivity depends on the presence of a complex microstructure, consisting of a Sm2(Co,Fe)17 cell phase, a cell boundary phase Sm(Co,Cu)5, and a Zr-rich platelet or lamellae phase. The aim of this work is to use electron back scatter diffraction (EBSD) in order to identify the different phases present in the isotropic magnets produced from cast alloys with the composition of Sm(CobalFe0.2Cu0.1Zrx)8, where x = 0, 0.02, or 0.06, and correlate them with th… 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.
