Abstract Scope |
Dissimilar laser welding of the CoCrFeMnNi to 316L stainless steel and Inconel 718 was successfully performed. Microstructure characterization by means of electron microscopy and high energy synchrotron X-ray diffraction were used to evaluate joint. Digital image correlation was used to evaluate how the different regions of the joints (base material, heat affected zones and fusion zone) deformed during tensile testing. High strength and ductility were obtained in the laser welded joints upon optimization of the process parameters. Thermodynamic calculations to analyze the microstructure evolution in the fusion zone of the welds was also performed and compared to the X-ray diffraction measurements.
A correlation between process parameters, microstructure evolution and mechanical properties was established.
The sound joints obtained in this work may open new potential applications for high entropy alloys in high demanding structural applications. |
