Effect of the Charge Mixing Time on the Magnetic Hysteretic Properties of a Hard Magnetic Powder Fe–30% Cr–8% Co Alloy

  • 1 Accesses

Abstract

The elemental mapping of a hard magnetic powder Fe–30Cr–8Co alloy prepared at different charge mixing times allows us to find that a homogeneous distribution of the components is reached upon mixing for 60 min. The dependence of the magnetic hysteretic properties of the powder Fe–30Cr–8Co alloy samples sintered at 1200°C on the mixing time exhibits logarithmic behavior. At the same time, the magnetic hysteretic properties of the same samples sintered at 1400°C are higher because of lower residual porosity and are independent on the charge mixing time.
