摘要: Abstract A study is made of the effect multistage treatment on magnetic hysteresis properties at room temperature and below high coercive (Nd 0.55 Ho 0.45 ) 2.7 (Fe 0.8 Co 0.2 14 B 1.2 alloy including melt spinning (MS), severe plastic deformation (SPD) heat (HT). It shown that SPD HT MS samples improves rectangularity second quadrant part loop resulting in a more than 25% increase maximal energy product as compared to ordinary processing. The observed changes are discussed modelled within framework Stoner-Wohlfarth theory magnetization reversal processes uniaxial ferromagnets.
