Recently, the United States Department of Energy has invested many millions of dollars to enhance, protect, and forecast their production and management. The work presented here attempts to clarify the limited and contradictory literature on the oxidation behavior of the ...

During the liquid metal extraction reaction between a Nd-Dy-Fe-B magnet and Mg, Nd rapidly diffuses out of magnet, whereas Dy is not extracted due to with matrix formation Dy2Fe17 phase. In addition, theDy2O3 phase exists at grain boundaries. Until now, only effect Dy2O3 on has been reported. this study, from was investigated in Mg. The during Mg (RE2Fe14B) first examined using thermodynamical ...
