| Abstract: | The criteria of amorphous formation for binary alloys presented by Ouyang Yifang et al were used to study the iron based binary alloys, which including the alloys composed of iron and transition metals, rare earth metals, noble metals, aluminum and lead. The ability of amorphous formation for these alloys are obtained. The results of theory and experiments are compared. The results of Zhang Hen's model are also included. A good agreement is obtained. The results are very useful for making amorphous Fe based powders. |
