Materials for Additive Manufacturing

Additive manufacturing has a great importance for industrial production of specific components. One of the most common procedures for additive manufacturing of metals is laser powder bed fusion (LPBF). However, the use of this method for high carbon steels is limited due to the formation of cracks and/or anisotropic microstructures. Both effects diminish the mechanical stability of the produced materials. By the additivation of carbides to the steel powders, the microstructure can be tailored thus circumventing the mentioned problems. The aim of this project is the implementation of a novel method of carbide additivation to hard ferrous alloys via a funtional polysaccharide-based binder. Thereby, the tendency to cold and hot cracking will be reduced and a homogeneous isotropic and fine-grained microstructure will be obtained.
