摘要

Magnetic properties of Sm-Fe(Ti)-C(N)/alpha-Fe nanocomposite alloys prepared by mechanical alloying (MA) have been studied. The hysteresis loops of MA Sm12Fe74Ti7C7Ndelta, Sm10Fe76Ti7C7Ndelta and Sm19.0Fe66.7C14.3 (i.e. Sm20Fe70C15) made by different processes (annealing, nitriding and re-milling) were measured at the applied magnetic fields with different dH/dt at 400, 350 and 295 K. The main phase with hard magnetic properties is of TbCu7-type. These three alloys have different behaviours of magnetization processes when the magnetic fields with dH/dt = 31.6 and 94.7 MA ms(-1) are applied. The magnetic viscosity S-v of Sm12Fe74Ti7C7Ndelta, Sm10Fe76Ti7C7Ndelta and Sm20Fe70C15 is determined from hysteresis loops measured for different dHIdt at various temperatures. The magnetic viscosity S-v in the Sm-Fe(Ti)-C(N)/alpha-Fe alloys is approximately proportional to the coercive field iH(c) at the measuring temperature. [References: 12]
