Effect of quenching temperature on orthorhombic boride formation at crystallization of amorphous ribbons Fe82B18

Crystallization of the amorphous ribbons Fe82B18 quenched from different temperatures of the melt occurs by various mechanisms. Thus, the amorphous ribbons obtained from quenching temperature below the structural changes in the liquid state are crystallized with formation of the α-Fe and Fe3B tetragonal phase. While, only the amorphous ribbons obtained from quenching temperature above the structural changes in the liquid state are crystallized with formation of the Fe3B orthorhombic phase besides the α-Fe and Fe3B tetragonal phase.
