摘要: Relationship between coercivity and microstructural changes during desorption-recombination (DR) treatment in the hydrogenation-decomposition-desorption-recombination (HDDR) processed NdFeCoB alloy has been studied by a combination of different experimental methods. In early DR stage, was very small after certain period treatment, abruptly increased. The corresponding positron lifetime spectrum, X-ray diffraction (XRD) thermal desorption spectrum (TDS) were measured. suggest that an Nd-rich phase formed among recombined Nd2(Fe,Co)14B grains plays important role for onset Nd-Fe-Co-B HDDR-processed alloy.
