摘要

In this paper the microstructure, magnetic properties and mechanical studies results for Fe61Co10Zr2+xHf3-xW2Y2B20 (for x = 1, 2 or 3) alloys are presented. The samples used in the investigations were obtained by a suction-casting method. The samples were produced in the forms of rods with diameter of 1mm and length of about 20mm and plates with thickness of 0.5mm and surface area of about 100mm(2). The results show that the best soft magnetic properties were achieved by Fe61Co10Zr3Hf2W2Y2B20 amorphous alloy in the form of a plate. This sample has the highest value of saturation magnetization (1.09 T) and the smallest values of coercivity (H-C = 1.5 A/m) and core losses. All investigated samples of amorphous alloys were characterized by substantially greater values of microhardness and, unfortunately, slightly lower values of wear resistance compared with their crystalline counterparts.
