LaFe13−xSixHz alloys are promising candidates for room temperature magnetic refrigeration, but their brittle behaviour hinders their shaping into magnetocaloric devices. Metal bonding of LaFe13−xSixHz particles has been performed to overcome this issue, but the fabrication processes reported so fa...
低Si含量的LaFe13-xSix合金(x≦1.6)具有原材料成本低廉、不含有毒元素、磁热性能优良的特点,是一种大有希望的室温磁制冷材料。LaFe13-xSix的居里温度在200K附近,通过吸氢和适量Co替代Fe元素均可将其调节到室温范围。LaFe13-xSix合金具有大磁热效应的前提是必须具有立方NaZn13型的晶体结构。由于熔炼时包晶反应...
