| Abstract Scope |
Both 316L stainless steel and copper (Cu) are extensively used in engineering applications, and understanding their interfacial behavior is crucial for robust joint formation. This study examines the impact of processing parameters on the joining strength of 316L-Cu interfaces in multi-material laser powder bed fusion (LPBF). The effects of laser power and scanning speed on joining strength were systematically analyzed through experiments. The 316L-Cu interfaces were characterized using optical microscopy, SEM, EDS, and micro-indentation to assess morphology and interfacial features. Mechanical testing evaluated the tensile strength of the joints under different processing conditions. Additionally, simulations of melt pool dynamics during LPBF provided insights into the two-phase interfacial behavior. This research aids in optimizing processing parameters for strong, reliable joints in multi-material LPBF, enhancing its applicability in various industrial sectors requiring the integration of dissimilar materials. |
