摘要: Abstract The magnetic properties of die-upset forged FeNdB magnets with Nd content varying from 6 to 20 at% have been studied. It has found that the crystallographic alignment is only possible for containing more than 12 Nd, i.e. having a liquid grain boundary phase during deformation. This provides fast diffusion path atomic migration. mechanism texture formation considered be complex and comprise fracturing, dissolving unfavourably oriented crystallites, growth grains favourable orientation, as well renucleation new saturated phase.
