Significant changes in the properties of alloys are associated with the formation of oxides, including REM2О3, not only on the surface but also within their volume, which is due to the high chemical activity of rare-earth metals. The data presented in this study will ...
Recent research efforts have focused on developing novel high-entropy alloys (HEAs) with exceptional mechanical properties through strategic metalloid alloying. Among metalloids, germanium exhibits a significant difference in atomic size and electronic structure with transition metals, which, in conjunction wi...
High entropy alloys (HEAs) are new class of metallic materials with five or more principal alloying elements. Due to this distinct concept of alloying, the HEAs exhibit unique properties compared to conventional alloys. The outstanding properties of HEAs include increased strength, superior wear resist...
High-entropy alloys with composition of AlCoCrFeNiTi( x: molar ratio; x = 0, 0.2, 0.4) under quasi-static and dynamic compression exhibit excellent mechanical properties. A positive strain-rate sensitivity of yield strength and the strong work-hardening behavior during plastic flows dominate upon...
The paper investigates the influence of several alloying elements (Al, Mn, Cu, Ti and Si) and the typology of the as-cast structure on the mechanical properties of high entropy alloys. A theoretical criteria analysis was carried out on the Al–Cr–Cu–Fe–Mn–Ni, Al–Cr–Co–Fe–Ni–...
The effects of atomic size difference on the microstructure and mechanical properties of single face-centered cubic (FCC) phase high-entropy alloys are studied. Single FCC phase high-entropy alloys, namely, CoCrFeMnNi, Al0.2CoCrFeMnNi, and Al0.3CoCrCu0.3FeNi, display good workability. The recry...
