Efficient Nanostructuring of Isotropic Gas-Atomized MnAl Powder by Rapid Milling (30 s)
An unprecedentedly short milling time of 30 s was applied to gas-atomized MnAl powder in order to develop permanent magnet properties and, in particular, coercivity. It is shown that such a short processing time followed by annealing results in efficient
