Abstract Scope |
This study investigates the microstructure and mechanical properties of the quaternary AlCoCrNi high-entropy alloy, prepared through the arc melting method. The alloy exhibits a microstructure with two phases: dendritic and inter-dendritic areas. After annealing at various durations, grain growth in the inter-dendritic area and phase transformation in the dendritic area were observed. The composition of alloys revealed a good distribution of elements, with Al and Ni concentrated in dark regions and Cr-rich regions in bright areas. Mechanical tests conducted on both as-cast and annealed samples at room temperature showed a significant increase in yield strength after annealing, ranging between 1,8 and 2,9 GPa. This comprehensive analysis of the crystal structure, microstructure, and mechanical properties delves into the quaternary AlCoCrNi alloy using the high-entropy concept. |
