Abstract: 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.The 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 the melted zone.Results presented in this paper have giv- en hint to remove free Fe in as—cast Nd_2Fe_(14)B alloy.

Key words: Nd-Fe-B alloy, laser/electron beam processing
