| Summary: | This study investigates the effects of varying Al content on the microstructure, mechanical performance, and corrosion resistance of AlxCuCrTiV (x = 1.7, 2.7) high-entropy alloys (HEAs) prepared using vacuum arc melting. Advanced characterization techniques and testing methods were employed to elucidate the role of Al content in phase evolution, lattice distortion, and performance optimization. Results indicate that the alloys exhibit BCC + FCC + HCP structures, with Al addition enhancing lattice distortion and strengthening properties, while also promoting phase transitions. Increased Al content also improved corrosion resistance, reducing corrosion current density and increasing charge transfer resistance by suppressing Cu-rich phase segregation. |
