The demands of high-performance industries such as aerospace, automotive, oil and gas industries are driving innovation in high performance materials and their production methods. In this project the effects of hybrid manufacturing, in particular the influence of the addition of tungsten carbide (WC) by means of Laser Metal Deposition (LMD), on the mechanical properties, hot workability and microstructure of the nickel-based superalloy Inconel625 (IN625) will be investigated. IN625 is known for its high temperature and high corrosion resistance, WC for its high wear resistance and grain refining effect. The integration of WC particles into the IN625 matrix, additionally using the hybrid approach of additive manufacturing and forging process, significantly influences the microstructural and mechanical behavior of the material. While the inclusion of WC can strengthen the material and extend the mechanical limitations, the full impact, including potential uses, should be thoroughly evaluated to qualify the material for the intended application. In order to understand the effect of the WC addition, the additive manufacturing of IN625 samples with and without WC as well as the forging of them will be carried out, their microstructures will be analyzed and modified by heat treatment. Subsequently hot isostatic compression tests, tensile tests, wear and creep tests will be carried out and the results will be analyzed and mapped. This research will contribute to the growing knowledge on hybrid manufacturing processes and material design and provides valuable information for high-performance industrial applications.
