以铁、硅和铝为基的合金具有高的磁导率和电阻率以及相当低的矫顽力,同时还有大的脆性损坏倾向,后者使其使用强度指标下降。对预合金强度性能的研究发现了其碎裂特性,但至今该类合金工程强度低的原因还未系统地研究过。按理论观念来说,合金具有脆性破坏的趋向大多是与能级电子 Iron, silicon and aluminum-based alloys have high permeability and resistivity as well as relatively low coercivity, along with large tendency to brittle failure, which decreases their use strength index. Studies on the strength properties of prealloyed alloys have found their fracture properties. However, the reason why the strength of such alloys has so far not been systematically studied. In theory, alloys tend to be brittle and mostly tend to be electron-energetic
