DIRECTIONAL SOLIDIFIED/HOT PRESSED R-Fe-B PERMANENT MAGNET ALLOY
|
Abstract:
Anisotropic directional solidified/hot pressed R-Fe-B permanent mag-net alloys are prepared and investigated.The typical composition of the alloys isPr_(19)Fe_(74.5)B_5Cu_(1.5).After directional solidification,a fine-grained columnar structure parallelto
