Erika Barreto - a research associate in the Spray Compacting and Metal Atomisation Department and part of Dr.-Ing. Nils Ellendt's working group, receives the Keynote Paper Award at World PM2022 in Lyon.

The World PM Congress & Exhibition is organised by the European Powder Metallurgy Association (EPMA) and brings together more than 1,000 visitors from the powder metallurgy industry each year.

Barreto's paper, entitled "Influence of oxygen in the production chain of metallic glasses via laser powder bed fusion", addresses the question of how oxygen contamination affects the processability of metallic glasses in 3D printing. For example, alloy elements of lower purity can be used in the application to significantly reduce material costs, among other things.Metallic glasses are high-end alloys that have outstanding mechanical and functional properties due to their amorphous structure. In order to synthesise these materials, high cooling rates are required, which can hardly be achieved with classic processes such as casting. Additive manufacturing can overcome the resulting size and geometry limitations and open up new fields of application.

The article to the presentation is published in the renowned journal Powder Metallurgy.
