THE REVERSIBLE VARIATION IN COERCIVITY FOR RARE EARTH-COBALT PERMANENT MAGNETS

摘要: 用磁性測量,透射電鏡,x射線衍射分析等方法研究了燒結SmCo₅和Sm(CoCuFeZr)_~7.0合金矯頑力可逆變化和不可逆變化的規律和顯微組織,并討論了造成這種可逆變化之原因。

Abstract: The reversible change and irreversible change in coercivity and mioros-tructure for sintered SmCo₅ and Sm(Co, Cu, Fe, Zr)7.0 alloy were studied by magnetic measurement, transmission electron microscopy (TEM) and X-ray diffractions.The causes which lead to these reversible changes have be en discussed.
