thermo-mechanical treatment of alcocrfeni2.1 high-entropy alloy

In this study, the microstructural evolutions, formed phases, micro- and macro-hardness changes and shear properties were evaluated in the as-cast, homogenized, cold-rolled and annealed alcocrfeni2.1 eutectic high-entropy alloy (ehea). these studies were carried out using x-ray fluorescence (xrf), scanning electron microscopy (sem), rockwell c and vickers hardness testing as well as shear punch testing (spt). the microstructure after cold rolling followed by annealing was consisted of an elongated phases/grains in the direction of cold rolling and in almost equiaxed phases/grains. the homogenized specimen has the minimum amounts of hardness and yield/ultimate shear strength. due to the presence of both elongated and equiaxed structures in the cold-rolled and annealed sample, the hardness and yield/ultimate shear strength of this specimen is between that of as-cast and homogenized cases
