Bulk metallic glasses are a new class of materials. These amorphous metals have a disordered structure, resulting in outstanding properties when compared to crystalline materials such as high hardness, strength, elasticity, good corrosion resistance, and superior soft magnetic properties. The properties of metallic glasses depend on alloy composition and cooling conditions during solidification. The required cooling rates to obtain an amorphous solid are limited, restricting product dimensions. Geometric limitations can be overcome by powder synthesis and consolidation. Gas atomization is a promising technique in the commercial production of metallic glasses, as amorphous particles can be produced. The aim of this PhD thesis was the development of novel cooling strategies for the atomization of glass-forming alloys. The focus was on the atomization of soft ferromagnetic glass-forming alloys with commercial purity. These alloys are difficult to atomize into an amorphous state due to cooling rate limitations and their low glass-forming ability. For this purpose, it was necessary to extend the common process window in gas atomization. This resulted in amorphous particles that normally tend to crystallize during droplet solidification. With the development of novel cooling strategies, new process windows have been made available that are typically inaccessible in conventional gas atomization. Four strategies were developed for the atomization of glass-forming alloys: (i) increasing the melt superheat temperature, (ii) hot gas atomization, (iii) spray cone cooling, and (iv) liquid quenching. The developed cooling strategies were used to decrease potent nucleation sites in the melt, to produce smaller particles, and to increase the heat transfer coefficient.weiterlesen
