摘要: Structure and magnetic properties of both melt-spun hot deformed bulk Sm–Co type nanocomposite magnets have been investigated with various metal additions, including Zr, Cu, Nb. The Zr Nb additions play important roles in constraining grain growth, resulting an increase coercivity Hc. Cu addition significantly improves the squareness BH loops as well energy product (BH)max. A typical anisotropic SmCo magnet Mr(hard)∕Mr(easy)∼0.4, Hc∼9kOe (BH)max 13.2MGOe was obtained.
