Production of D2 and 17-4 PH Bimetallic Materials and Investigation of Their Mechanical Properties in Atomic Diffusion Additive Manufacturing Method

The study focused on the production of bimetallic material from 17-4 stainless steel and D2 tool steel using the Markforged brand Metal X device. In particular, despite the different physical and mechanical properties of the materials used, studies were carried out on the production of bimetal and the interfacial behavior thanks to the use of different filaments. The sample designed in cylindrical geometry was printed using layer-by-layer extrusion. Then, a debinding and sintering process was performed according to the ADAM (Atomic Diffusion Additive Manufacturing) methodology. In particular, the sample was passed through the production stages in a vertical position to ensure interface compatibility and prevent agglomeration. The produced sample's density, hardness, and microstructure properties were examined. According to the results, bimetal and hybrid material production can be carried out using the Metal X device.
