| 摘 要： | 采用拉拔变形法制备了Cu-Fe-Cr原位复合材料,并从线材中提取出Fe-Cr纤维。用扫描电镜观察了复合线材和纤维的微观形貌,并用VSM对复合线材和Fe-Cr纤维进行了磁性测试,绘制了磁滞回线。结果表明:复合线材具有磁各向异性,其易磁化方向平行于线材轴向;随着变形量的增大,复合线材的剩磁和矫顽力逐渐增大;Fe-Cr纤维的比饱和磁化强度Ms达到了150 emu.g-1,是一种有潜在应用价值的吸波材料。

| Abstract: | Cu-Fe-Cr in-situ composite wires were manufactured by cold drawing and Fe-Cr fibers were extracted from them.The microstructure of composite wires and fibers were observed by SEM,and the magnetic property of the composite wires and Fe-Cr fibers were tested by VSM,and then the hysteresis loops were determined.It shows that the composite wires had magnetic anisotropy paralleling to the long axis of wires;the M_r and the H_c of the wires increased with deformation increasing;the M_s of fibers was 150 emu·g~(-1),whose fibers may be used as an electro-magnetic wave absorbing material. |
