It was found that the free Fe in the melted zoneof the as—cast Nd_2Fe_(14)B alloy could be dissolved byIaser/electron beam.The growth direction ofNd_2Fe_(14)B grains is nearly perpendicular to the sur-face of the samples.EDX examination showed thatFe element was homogeneously distributed in themelted zone.Results presented in this paper have giv-en hint to remove free Fe in as—cast Nd_2Fe_(14)B alloy.
It was found that the free Fe in the melted zone of the as-cast Nd_2Fe_ (14) B alloy could be dissolved by Iaser / electron beam. Growth direction of Nd_2Fe_ (14) B grains is nearly perpendicular to the sur-face of the samples. EDX examination showed that Fe element was homogeneously distributed in theme zone. Results have in this paper have giv-en hint to remove free Fe in as-cast Nd_2Fe_ (14) B alloy.
