The process of blending powders using stirring blades involves complicated granular flows, particle‐scale mechanisms, and blade–particle interactions, which is challenging to predict and control. This article proposes a continuum‐based model for such a process by incorporating the flow rheology, isotropic particle diffusion and the percolation of granular materials. A method combining finite element...
It is conventionally accepted that cerium can weaken the magnetic behavior of the Nd-Fe-B magnets. In the present work, however, it is found that the coercivity increases only with the addition of 20 at.% of cerium into the Nd-Fe-B alloy using physical performance measurement system compared to other samples with less or more Ce additions. Unique microstructure and phase composition for the 20 at...
