KW - magnetic powders, SC alloy flakes, HDDR process, anisotropy.
AB - <p style="text-align: justify;">Both non-homogenization treatment Zr, Ga addition and ternary Strip Casting
alloy flakes can be used to prepare anisotropy HDDR NdFeB magnetic powders.
This illustrates that anisotropy formation of magnetic powders neither depends on
element addition nor depends on homogenization heat treatment of SC flakes. But
the HDDR process procedure also plays an important role in anisotropy inducement.
Highly anisotropic magnetic powders are attributed to rapid disproportionation reaction
course, slow desorption-recombination reaction course, and optimum recombination
hydrogen pressure during HDDR procedure process. This paper will provide an
important guidance for preparing highly anisotropy magnetic powders with low cost.</p>
