چکیده مقاله
In this study, two high entropy alloys of AlCoCrFeNi Al1 and Al0 7CoCrFeNi Al0 7 , werecladded on plain carbon steel using the gas tungsten arc welding process at a welding currentof 180 A and a welding speed of 1 4 mm/s Clads microstructures and types of cracks havebeen investigated by a combination of optical microscopy OM , field emission scanningelectron microscopy FESEM , X ray diffractometry XRD analysis, and microhardnessmeasurements Results indicate that the Al1 clad has a petal like structure of the BCC and Crrichphases Both intergranular and transgranular cracks were identified in the Al1 alloy Thetype of cracks were assumed to be a solidification cracking By reducing Al in the Al0 7 alloy,the Cr rich phase was eliminated, and a new phase with the FCC crystal lattice formed invarious morphologies A combination of factors, including a decrease in the solidificationrange, formation of the FCC phase, and reduction in hardness, were attributed to crackelimination in the Al0 7 alloy
