Abstract

The crystallization behavior of amorphous Fe_90-xNb₁₀B_x alloys was investigated. The relationship between the stability of supercooled liquid state and the phases formed upon crystallization was studied. The phase transformation behaviors were explained by a hypothetical free energy diagram for Fe-Nb-B alloys. By considering the local atomic structures of the amorphous and crystalline phases, the difference in the difficulty of the geometrical rearrangement for the precipitation of primary crystalline phases was found to coincide with the differences in the thermal stability of the amorphous Fe-Nb-B alloys.
