Glass forming ability and magnetic properties of Nd48Al20Fe27Co5 bulk metallic glass with distinct glass transition

Nd48Al20Fe27Co5 bulk metallic glass (BMG) was prepared in the shape of rods 3 mm in diameter by suction casting. In contrast to the previously reported hard magnetic Nd–Al–Fe–Co BMGs, the Nd48Al20Fe27Co5 as-cast rod exhibits a distinct glass transition, multi-step crystallizations in DSC traces and much lower coercivity. The glass forming ability as well as the kinetics of the glass transition and crystallizations of the Nd48Al20Fe27Co5 as-cast rod have been studied. The magnetic properties of the alloy were investigated in comparison with Nd60Al10Fe20Co10 glass forming alloys.
