چکیده انگلیسی
The effects of cold rolling on the evolution of microstructure and the mechanical behavior of Al0.25CoCrFeNi high-entropy alloys were investigated. Cold rolling resulted in extensive grain elongation, formation of deformation bands within the grains, and development of crystallographic textures that depended on the rolling reduction. The textures were investigated by electron backscattered diffraction after cold rolling. The present cold-rolled alloy indicates a strong brass-type texture. Cold rolling results in a substantial strengthening of the alloy; its ultimate tensile strength approaches 1479 MPa, which was 2.8 times of that in the as-cast condition, but at the expense of low ductility (ε ~ 2.3%).
