ABSTRACT

The crystallization kinetics of the melt-spun Fe-Zr metallic glasses in the iron-rich region has been investigated by means of DSC and X-ray diffraction. The crystallization mode changes with iron concentration. In the lower iron region, 20 ⩽ x ⩽ 25, the FexZr100−x glasses crystallize into ω-Zr and Ti2Ni-type FeZr2 with an accompanying sharp and large exotherm at the first crystallization step and immediately after this step, they transform into orthorhombic FeZr3. On the other hand, the alloys with 35 ⩽ x ⩽ 40 exhibit a gradual exotherm which initiates from a temperature far below the definite crystallization temperature (Tx). The Fe-Zr metallic glasses in this concentration region crystallize polymorphously into the oxygenstabilized Ti2Ni-type FeZr2 with accompanying relatively small and composite exotherms. The annealing at a temperature where the gradual exotherm occurs for the alloys with 30 ⩽ x ⩽ 40 does not cause any changes of X-ray halo pattern but results in the reduction of the heat of exotherm due to the crystallization.
