Influence of heat treatment on the efficiency of impact fragmentation of amorphous alloy Fe73.5Cu1Nb3Si13.5B9 ribbons
Abstract
The mechanism of impact fracture of soft magnetic amorphous alloy Fe73.5Cu1Nb3Si13.5B9 ribbons in a disintegrator after heat treatment at a temperature from the range 300-700°C and the fractional composition of the formed powder are studied. The temperature ranges of a change in the mechanism of ribbon fracture are determined. The particle size distribution is shown to change weakly within the revealed temperature ranges.
