Effects of Heat Treatment on some Magnetic Properties of Amorphous Alloys Containing Fe49Ni29Si9 B13 and Fe59Ni19Si9 B13

Abstract

The effect of various processing modes on the magnetic properties of amorphous Fe49Ni29Si9B13 and Fe59Ni19Si9 B13 alloys obtained by melt spinning was examined. Samples from both alloys were prepared separately in the magnetic field and without the field. An increase in soft magnetic properties was observed during the period of the transition to the crystalline phase, (Hc = 50 A/m, Br = 2.16 Tl). After crystalline phases are formed, materials lose their soft magnetic properties. The composition of samples of rapidly cooled various Fe and Ni containing alloys were tested on XRD. Shimadzu XRD 6000 diffractometer was used to determine the phases of amorphous alloys by applying Cu Ka radiation at 40 kV/30 mA (CuKa1 = 122.59 A/m). Kβ radiation is eliminated by graphite monochromator
