摘要
基于输电线路抗覆冰的应用背景,通过对Fe100-x-yCrxBy(x=11～20,y=9～20)的成分调节和快淬工艺参数控制,制备了同时具有低居里温度和高饱和磁极化强度的非晶带材.测试研究表明Fe65Cr15B20和Fe64Cr16B20的居里温度分别为28.6和11.6℃,Fe65Cr15B20和Fe64Cr16B20在0℃的饱和磁极化强度分别为0.69和0.62 T.设计组装了一种近似绝热磁致热功率的测量装置,用该装置对Fe65Cr15B20和Fe64Cr16B20两种非晶合金带的磁热功率进行了近似测量和分析.
Fe100-x-yCrxBy（x = 11-20, y = 9 -20） amorphous ribbons with low Curie point and high saturation magnetization, which could be applied in anti-icing in transmission lines, were prepared by rapid-quenching with various technological parameters. Experimental results show that the Curie temperatures of Fe65Cr15B20 and Fe64Cr16B20 amorphous ribbons are 28.6 and 11.6 ℃ , while the saturation magnetizations of Fe65 Cr15 B20 and Fe64 Crl6 B2o amorphous ribbons are 0.69 and 0.62 T at 0 ℃ , respectively. Magnetocaloric effects of Fe65 Cr15 B20 and Fe64 Crl6 B20 amorphous ribbons were approximately measured and analyzed by using a self-designed apparatus on the basis of the near heat-insulation method.
