Abstract:
This study investigates thermomechanical post-processing techniques, including deep cryogenic treatment and annealing heat treatment, to enhance the mechanical strength of a selective laser melted (SLMed) CoCrFeMnNi high-entropy alloy. The alloy exhibits high strength, corrosion resistance, and ductility, making it suitable for aerospace, automotive, and biomedical applications. The research utilizes SEM and TEM microscopy techniques for microstructural analysis. Fracture toughness is evaluated using SENB, while high strain rate impact and hardness tests assess dynamic behavior. The results provide insights into the effects of thermomechanical processing on the alloy's mechanical properties, contributing to the optimization of high-entropy alloys produced via selective laser melting. This study advances additive manufacturing knowledge and facilitates the development of robust metallic components for diverse industries. |
