摘要: The effect of Mn on hydrogenation behavior and magnetic properties 2:17 type SmCo alloys was investigated. as-cast Sm(Cobal.Fe0.2Mn x Cu0.08Zr0.025)7.2 with $x = 0$ , 0.04, 0.08, 0.12 were all decrepitated under hydrogen pressure 0.3 MPa at room temperature. ability obviously improved the increase content. size particles decreased content due to network structure diminishing increasing. phase microstructure changes discussed. Research results show that Mn-doped has a great grain boundary phase, which lead high absorption broken alloys. following obtained for Sm(Cobal.Fe0.2Cu0.08Mn0.04Zr0.025)7.2 magnet: $B_{r} 10.6$ kGs, $H_{\text {cj}} 28.35$ kOe, $(BH)_{\mathrm {\mathbf {max}}} 26.74$ MGOe.
