Increasing the amorphous yield of {(Fe0.6Co0.4)(0.75)B0.2Si0.05}(96)Nb-4 powders by hot gas atomization

摘要

The synthesis of metallic glasses requires high cooling rates leading to product size limitations of a few millimeters when using conventional casting techniques. One way to overcome these size limitations is powder metallurgy. Melt atomization and the subsequent powder processing can result in larger, amorphous components as long as no crystallization takes place during powder consolidation.
