Magnetic properties and phase composition of nanocomposite rapidly hardened Nd9.5Fe84B6M0.5 (M: Ti, Zr, Cr, Mo, Cu) STRIPS

  • Published:
Metal Science and Heat Treatment Aims and scope

Analysis of the effect of replacement of iron atoms with atoms of alloying components on the hysteresis properties of rapidly hardened alloys Nd9.5Fe84B6M0.5 (M: Ti, Zr, Cr, Mo, Cu) is performed. The laws of variation of the hysteresis properties as a function of the temperature of crystallization annealing of the rapidly hardened alloys are determined. Correlations between the hysteresis properties and the phase and structural state of rapidly hardened specimens are studied. The special features of formation of the hysteresis characteristics are discussed with allowance for the possible implementation of an exchange-bonded state in nanocrystalline specimens.
