| 摘要 | Al90Ni2Y8 and Al84Ni8Y8 alloy ribbons were produced by melt-spinning, the structural characterization of the as-quenched samples was performed by XRD, the thermal stability of the as-quenched alloys was characterized using a differential scanning calorimeter (DSC), the magnetism of both Al90Ni2Y8 and Al84Ni8Y8 alloys fully amorphous and partially crystallized were investigated using a superconducting quantum interference device (SQUID). The results show that the magnetism of the amorphous Al90Ni2Y8 and Al84Ni8Y8 alloys are diamagnetism, and the alloys are magnetized more easily with higher Ni content. When the magnetic field reaches 0.5 T, the specific magnetizations of Al90Ni2Y8 and Al84Ni8Y8 alloy are -0.083 and -0.091 Am-2/kg, and the magnetisabilities are -1.66x10(-5) and -1.82x10(-5), respectively. The magnetism of alloys remains unchanged after partially crystallized, but the absolute value of specific magnetization is correspondingly increased. After partially crystallization, the absolute value of specific magnetization of the Al90Ni2Y8 alloy increases from 0.083 Am-2/kg to 0.231 Am-2/kg, and that of the Al84Ni8Y8 alloy increases from 0.091 Am-2/kg to 0.163 Am-2/kg corresponding to a magnetic field of 0.5 T, and also the absolute value of magnetisability reaches to 4.62 x 10(-5) and 3.26x10(-5), respectively, which is attributed to the Ni and Y elemental buildup around the nanometer sized pure Al crystals after partially crystallization. |
