  • Descrição: In the present study, the intelligent addition of Re and Al to TiZrHf equiatomic ternary alloy resulted in a new single-phase Ti 30 Zr 30 Hf 30 Re 5 Al 5 HCP high entropy alloy. The XRD analyses show that the TiZrHfRe x alloys have a single-phase HCP structure until x = 5 at.%. Subsequently, the TiZrHfRe 5 retains its single-phase HCP microstructure with the addition of Al upto 5 at.%, leading to a new quinary TiZrHfRe 5 Al 5 HCP HEA. Microstructural investigations using SEM revealed the formation of compositionally homogeneous single-phase HCP solid solution for TiZrHf, TiZrHfRe 5 and TiZrHfRe 5 Al 5 alloys. Vicker's microindentation measurements revealed that adding Re, followed by Al, increases the hardness of the TiZrHf ternary alloy from 7.85 0.37-8.35 0.42 GPa. In a nutshell, a novel quinary HCP alloy was developed based on transition metals, allowing HCP HEA compositional space to expand beyond rare-earth (RE) based HEAs.
