Weakly magnetic iron@-boron alloy contg. crystalline particles - exhibiting excellent magnetic properties at frequencies above 100 kHz

摘要

A nanocrystalline, weakly magnetic alloy in which mean crystalline particle dia. is max. 50 nm and having a supersaturated Fe-B solid soln. component, is new. Pref. the alloy also contains an amorphous phase, and at least several of the crystalline particles contain an Fe-Si phase. USE/ADVANTAGE - Weakly magnetic alloy with excellent performance at frequencies above 100 kHz, used for high-frequency transformers or inductance coils.
