Nitrogen-Induced Phase Separation in Equiatomic FeNiCo Medium Entropy Alloy

, 2022
We report the first observation of isothermal phase separation triggered by inwardly diffusing interstitial nitrogen atoms during nitriding of an equiatomic FeNiCo medium entropy alloy. Detailed microstructural characterization revealed a phase-separated

On the strength and fracture toughness of an additive manufactured CrCoNi medium-entropy alloy [PDF]

, 2023
An additively manufactured (nominally equiatomic) CrCoNi alloy was processed by laser powder bed fusion (LPBF). At ambient temperatures (298 K), this medium-entropy alloy displayed a yield strength, σ y of ∼691 ± 9 MPa, and an ...

Mechanical Behavior of a Medium-Entropy Fe65(CoNi)25Cr9.5C0.5 Alloy Produced by Selective Laser Melting

, 2023
Specimens of a medium-entropy Fe65(CoNi)25Cr9.5C0.5 (in at.%) alloy were produced using additive manufacturing (selective laser melting, SLM). The selected parameters of SLM resulted in a very high density in the specimens with a residual porosity of ...

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

Cantor-derived medium-entropy alloys: bridging the gap between traditional metallic and high-entropy alloys

Journal of Materials Research and Technology, 2022
The year 2004 marked the beginning of a new era in the design of metallic materials, as the concept of multiple principal component alloys, commonly known as High-Entropy Alloys (HEAs), was proposed by Cantor and Yeh. The unexpected single-phase microstructure, instead of the expected brittle intermetallic compounds, was attributed to the large entropy

Advances in High-Entropy Alloys’ Microstructure, Properties and Preparation

Metals
High-entropy alloys (HEAs), medium-entropy alloys (MEAs), and related multi-principal-element materials have significantly broadened the conceptual framework of alloy design by moving beyond conventional alloy systems centered on one principal element [..
