%X High entropy alloys (HEA) are novel advanced materials that have been subjected to extensive research due totheir outstanding properties and potential for key engineering applications. Given this, research on their processabilitymust be conducted to avoid premature failure during operation. Gas tungsten arc welding is a widelyavailable technology capable of generating high performing and permanent joints. Furthermore, within thistechnology, dissimilar welding is a relevant topic given the frequent necessity to join different materials,allowing for greater design freedom while decreasing material costs. In this study, dissimilar welding of aFeMnCoCr HEA with a Fe-based shape memory alloy was conducted, allowing an inquiry into the compatibilitybetween the two advanced engineering alloys. By employing both conventional and advanced characterizationtechniques, including optical and electron microscopy, atom probe tomography and synchrotron x-ray diffraction,a comprehensive understanding of the effect of processing condition on the microstructure and mechanicalresponse of the joints is obtained. With this work we intend to highlight a pathway for the introduction of HEAsin modern day engineering industry.
