  • Abstract
    Effect of particle size on the disproportionation of the Ga-stabilized Sm2Fe15Ga2 alloy was examined using a DTA and TPA under hydrogen gas, it was revealed that the hydrogen-assisted disproportionation of the Ga-stabilized Sm2 Fe15Ga2 alloy was influenced significantly by its particle size. The Sm2Fe15Ga2 alloy powder with finer particle size (<40 μm) was completely disproportionated by heating up to 800°C under hydrogen even with moderate pressure (1.8 kgf/cm2)
