摘要：

The　effect　of　doping　Cu　on　the　mechanical　properties　and　magnetic　properties　of　Sm(Co0.71Fe0.15Cu0.07Zr0.03)7.6　magnets　was　studied　systematically.　The　results　show　that　the　Cu-lean　grain　boundaries　and　bending　strength　of　the　magnet　can　be　improved　by　increasing　of　doping　Cu　content.　The　optimal　magnetic　properties　of　magnet　with　1.0　wt%　Cu　doping　are　$B_{\mathrm　{r}}　=9.9$　kG,　$H_{\mathrm　{cj}}　=23.0$　kOe,　and　(BH)　$_{\mathrm　{max}}　=　22.2$　MGOe.　With　the　doping　content　of　Cu　powders,　the　bending　strength　first　reaches　a　peak　value　of　143.0　MPa　at　1.0　wt%　and　then　drops.　The　bending　strength　of　the　magnet　with　1.0　wt%　Cu　doping　is　about　51.8%　higher　than　that　of　the　magnet　with　0　wt%　Cu　doping.　The　coercivity　and　bending　strength　of　the　magnet　are　improved.　©　1965-2012　IEEE.
