Mechanical Properties of X3NiCoMoTi 18-9-5 Produced via Additive Manufacturing Technology – Numerical and Experimental Study

The purpose of the article is to analyze the influence of print orientation, using the DLMS method, on the strength of the tested material before and after heat treatment. The heat treatment involved heating the material to 490˚C and subsequently cooling it within the furnace for four hours. Experimental research involves X3NiCoMoTi 18-9-5 tool steel. Analysis of the test results indicates a strength increase following heat treatment. Additionally, a numerical study was conducted to investigate the mechanical characteristics of X3NiCoMoTi 18-9-5 tool steel fabricated via 3D printing. Fractographic analysis of specimen failure was performed, and the results were subsequently compared.
