摘要
Fe-6.5%Si高硅钢是一种具有高磁导率、低矫顽力和低铁损等优异软磁性能的合金,但是其室温脆性和低的热加工性能严重影响了其在工业领域的应用。综述了Fe-6.5%Si高硅钢的性能,评述了合金的改性法、特殊轧制法、快速凝固法、沉积扩散法、粉末冶金法等制备工艺。
It is well known that 6.5 %Si high silicon steel is one kind of soft magnetic materials with higher re= lative permeability, lower coercive force and iron loss than those of conventional industrial silicon steel. However, their room-temperature embrittleness and poor workability limit their practical applications in the industry. The preparation technique such as modification treatment on alloy, special rolling, rapid solidification, CVD and powder me- tallurgy is reviewed.
