Influence of Surface Preparation on Cracking Phenomena in TIG-Welded High and Medium Entropy Alloys
Journal of Manufacturing and Materials Processing, 2021 Multi-element systems with defined entropy (HEA—high entropy alloy or MEA—medium entropy alloy) are rather new material concepts that are becoming increasingly important in materials research and development.

Tensile properties of high- and medium-entropy alloys [PDF]
Intermetallics, 2013 Abstract Equiatomic, face-centered-cubic, high- and medium-entropy alloys were arc melted, hot-rolled to produce recrystallized sheets, and tensile tested. The alloys having the compositions CrMnFeCoNi and CrFeCoNi exhibited a strong temperature-dependent decrease in strength with increasing temperature from −196 °C to 1000 °C, and a relatively weak ...

Superior Strength-Ductility Cocrni Medium-Entropy Alloy Wire [PDF]
SSRN Electronic Journal, 2020 Abstract High strength-ductility is the prerequisite requirement for the widely used steel wires in engineering applications. Traditional strengthening strategies on these wires are suffocated inevitably by strength-ductility trade-off dilemma. Recent emerging medium-entropy alloys (MEAs) usually exhibits excellent ductility but relatively lower ...

Design and development of (Ti, Zr, Hf)-Al based medium entropy alloys and high entropy alloys
Materials Chemistry and Physics, 2022 Abstract The design and development of TiZrHfAl medium entropy alloy (MEA), and the TiZrHfAlNb0.2 and TiZrHfAlV0.2 high entropy alloys (HEAs) is described. The combination of 4th subgroup elements (Ti, Zr, and Hf) with Al is discussed based on the periodic table and taxonomy of HEAs. The alloys were designed using alloy parameters for HEAs, predicted
