Metal Additive Manufacturing Conference - MAMC 2024

Additive manufacturing processes are becoming increasingly popular. Metal Binder Jetting (MBJ) is emerging as a promising technique for high productivity in the simultaneous production of highly complex components. The limited number of materials available for MBJ creates a high potential for research. Especially in the field of nickel-free austenitic stainless steels, the choice of materials is limited.
In this study, a newly developed metal powder X15CrMnMoNi17-11-3 was fabricated by MBJ and samples with a high density greater than 97,2 vol% were obtained. The mechanical properties due to sinter-based additive manufacturing microstructures were elaborated. After a hot isostatic pressing (HIP) post-treatment, an increase in strength of about 10% could be achieved. Microstructural analysis and thermodynamic calculations were used to explain this differences.
