Rapidly solidified nanocomposite SmCo7/fcc Co permanent magnets
High-remanent Sm-Co permanent magnetic alloys modified with Nb and C have been produced with isotropic grain structures consisting of 100-200nm SmCo7 and 10-15nm fcc Co phases, with the Co phase comprising only 2-4vol%. Remanence ratios of 0.7 have been consistently observed, with coercive forces ap...

Summary: | High-remanent Sm-Co permanent magnetic alloys modified with Nb and C have been produced with isotropic grain structures consisting of 100-200nm SmCo7 and 10-15nm fcc Co phases, with the Co phase comprising only 2-4vol%. Remanence ratios of 0.7 have been consistently observed, with coercive forces approaching 10kOe. |
