Structure and properties of melt-quenched manganese- and nickel-diamagnetic element systems

The choice of melt quenching temperatures from a single-phase region is justified by theoretical calculations of the positions of maxima of the immiscibility regions in liquid Mn-Pb, Ni-Pb, and Mn-Bi alloys, and the influence of an alloy composition and a high cooling rate on the phase formation in...

Description
Summary:The choice of melt quenching temperatures from a single-phase region is justified by theoretical calculations of the positions of maxima of the immiscibility regions in liquid Mn-Pb, Ni-Pb, and Mn-Bi alloys, and the influence of an alloy composition and a high cooling rate on the phase formation in these alloys and their magnetic properties is studied. The coercive force of an Mn-Bi alloy is shown to be increased by increasing the melt quenching temperature to 1923 K to form nanocrystals of the α-MnBi phase.
