Abstract
Magnetic properties, electrical resistivity and hardness were studied on Fe-Mo alloys containing less than 14.1%Mo and Fe-W alloys containing less than 13.8%W. All the alloys used in this study were water quenched from various temperatures at 900∼1200°C, cold drawn by more than 50% reductions in area, and then reheated at 400∼1000°C for less than 5 h.The results indicated that the magnetic properties of those alloys depended remarkably on the concentration of added Mo or W, the quenching temperature, the reduction rate, the reheating temperature and the reheating time. An Fe-10.2%Mo alloy reheated at 800°C for 30 min after water quenching from 1000°C and subsequent cold drawing of 97.2% reduction exhibited the following values: B8=1.62 T at 8 kA·m−1, Br=1.49 T, Br⁄B8=0.92, Hc=1.91 kA·m−1, \sqrt(BH)max⁄BrHc=0.83, ρ=0.251 μΩ·m and Hv=290. Also, an Fe-10.2%W alloy reheated at 700°C for 60 min after water quenching from 1000°C and subsequent cold drawing of 97.2% reduction exhibited the following values: B8=1.79 T, Br=1.71 T, Br⁄B8=0.95, Hc=1.75 kA·m−1, \sqrt(BH)max⁄BrHc=0.86, ρ=0.215 μΩ·m and Hv=275.
