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 ...

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 ...

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.

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.

Preparation of nanoporous CoCr alloy by dealloying CrCoNi medium entropy alloys

Journal of Materials Research and Technology, 2020
High/Medium entropy alloys (H/MEAs) represent a new strategy for the design of materials with properties superior to those of conventional alloys. Here, we show a new field of application where the uniform mixtures of multiple principal elements in H/MEAs is utilized to create new type nanoporous alloys by dealloying. By using equiatomic CrCoNi MEAs as

Coexistence of two types of short-range order in Si–Ge–Sn medium-entropy alloys

Communications Materials, 2022
Short-range chemical ordering has emerged as a key feature for controlling the properties of high-entropy alloys. Here, ab initio calculations reveal that two types of short-range ordering exist in Si–Ge–Sn medium-entropy alloys, suggesting that multiple
