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.

Electrodeposition of a CoNiCu medium-entropy alloy in a water-in-oil emulsion

Electrochemistry Communications, 2021
A medium-entropy alloy (MEA) of CoNiCu with a face-centered cubic structure was successfully obtained by electrochemical deposition. To achieve a nearly equiatomic composition, a water-in-oil emulsion was used as the solution for electrodeposition. Since

The effect of processing route on properties of HfNbTaTiZr high entropy alloy [PDF]

, 2019
High entropy alloys (HEA) have been one of the most attractive groups of materials for researchers in the last several years. Since HEAs are potential candidates for many (e.g., refractory, cryogenic, medical) applications, their properties are studied ...

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 ...

Effective Surface Nano-Crystallization of Ni₂FeCoMo_0.5V_0.2 Medium Entropy Alloy by Rotationally Accelerated Shot Peening (RASP)

Entropy, 2020
The surface nano-crystallization of Ni2FeCoMo0.5V0.2 medium-entropy alloy was realized by rotationally accelerated shot peening (RASP). The average grain size at the surface layer is ~37 nm, and the nano-grained layer is as thin as ~20 μm.
