The correlation between the grain refining effect of TiC on the microstructure of Pr2Co14B melt-spun ribbons and the magnetic properties is presented in this study. TiC enabled greater control of microstructure both in the as-spun and heat treated Pr

It is demonstrated that alloying additions of Ga and Ge enable tuning of the magnetocaloric response of the intermetallic boride AlFe2B2. Samples of nominal chemical composition Al1.2-xMxFe2B2 (M = Ga, Ge; x ≤ 0.30) were synthesized via suction cas

Magnetic property enhancement of alnico, a rare-earth free permanent magnet, is highly dependent on both the initial microstructure and the evolution of the spinodal decomposition (SD) inside each grain during the heat treatment process. The size, sh
