Dependence of the Phase Composition of Nd16Fe73.9Zr2.1B8 Alloy on the Conditions of Milling in Hydrogen

  • Published:
Materials Science Aims and scope

We reveal the competitive influence of two factors in the process of “dry” milling of Nd16 Fe 73.9 Zr 2.1 B 8 ferromagnetic alloy in hydrogen. As the rotation frequency of the mill chamber and the duration of the process increase, the range of particle sizes of the powder increases but particles become isotropic as a result of agglomeration. We indicate the possibility of application of a liquid medium (oleic acid) with an aim to prevent mechanical alloying of highly dispersed powder particles as a result of long high-energy milling. Highly dispersed anisotropic powders are obtained by milling of the alloy saturated with hydrogen in oleic acid at a rotation frequency of the mill chamber of 100–200 rpm for 12 h.
