根据河野、小岛等人的研究,要想获得好的磁性能必须使合金在高温状态能完全固溶成ε相(密排六方无序相)。然后通过适当热处理经过过渡相ε’(正交四方有序相),转变成τ相(面心正方亚稳铁磁性相)。 According to Kawano, Kojima et al.’s study, in order to obtain good magnetic properties, the alloy must be completely solid-solutioned into an ε phase (hexagonal disordered phase) at a high temperature. It is then converted to the τ phase (face centered square metastable ferromagnetic phase) by appropriate heat treatment through the transition phase ε ’(orthogonal tetragonal ordered phase).
