Abstract null null The microstructure and mechanical properties of as-cast and isothermally annealed CxHf0.25NbTaW0.5 (x=0, 0.05, 0.15, 0.25) refractory high-entropy alloys (RHEAs) were studied. Both the as-cast and annealed RHEAs consisted of disordered body-centered cubic solid solution phase and metal carbide (MC) phase with a face-centered cubic crystal structure (Fm-3m space group). The primary carbides were enriched with Hf and C elements and tended to form lamellar eutectic-like microstru...

Abstract null null In the present study, an Al–Ni–Mg ternary reaction was used to provide an improved interfacial structure of carbon fiber reinforced Al-matrix (CF/Al) composites fabricated by a rapid process in open space. Driven by ternary reaction, better infiltration behavior of Al matrix can be obtained. With increasing Mg element addition, the ternary reaction was enhanced with the formation of Al–Ni–Mg IMCs with gradually larger size. When the value is 2.5 wt%, the relative density incre...

Abstract null null NbMoTaW-based refractory high-entropy alloys (RHEAs) are now at the research frontier of advanced metallic materials due to outstanding mechanical properties at elevated temperatures. However, the poor plasticity of NbMoTaW-based RHEAs at room temperature hinders further development. The present work proposes a new strategy to tailor in-situ forming heterogeneous structures and improve the room-temperature mechanical properties of NbMoTaW-based RHEAs. A novel series of as-cast...

Abstract The top-down method was used to fabricate the TiNi1+xSn half-Heusler alloy. Several knotty problems have been solved using the top-down method, including the generation of impurity phases, the visible discrepancy in the grain size of the TiNi2Sn second phase, and irregular variations in the Seebeck coefficient (S), electrical conductivity (σ), and thermal conductivity (κ) with increasing Ni content. The generation of a large number of incoherent interfaces between the half-Heusler (HH) ...

Abstract The microstructure, bio-corrosion properties and cytotoxicity of as-extruded Mg–5Sn–xIn (x=0, 1, 2, 3, 4, all in wt%) alloys were investigated in vitro for biomedical applications. The results show that the microstructure of all alloys exhibits a partially recrystallized structure, and the area fraction of dynamically recrystallized (DRXed) grains increases with In addition. Mg2Sn particles are mostly precipitated at DRXed grains. Weight loss and potentiodynamic polarization measurement...

Abstract To evaluate the potential of high entropy alloys for marine applications, a new high entropy alloy coating of AlCrFeNiW0.2Ti0.5 was designed and produced on Q235 steel via laser cladding. The microstructure, microhardness and tribological performances sliding against YG6 cemented carbide, GCr15 steel and Si3N4 ceramic in seawater were studied in detail. The AlCrFeNiW0.2Ti0.5 coating showed an anomalous ‘sunflower-like’ morphology and consisted of BCC and ordered B2 phases. The microhard...

Abstract null null Eutectic high entropy alloys (EHEAs) have attracted considerable interest because of their excellent casting fluidity and outstanding mechanical properties. In this study, a novel system of EHEAs, namely CrFeNixV0.64Ta0.36 (1.3 ≤ x ≤ 1.9) was designed and prepared. The microstructure evolution and mechanical properties of CrFeNixV0.64Ta0.36 EHEAs were investigated in as-cast state. The results showed that the alloy was composed of σ-phase, Fe7Ta3-type intermetallic compounds (...

Recently, eutectic high-entropy alloys (EHEAs) have attracted considerable attention owing to their outstanding mechanical properties and excellent castability. However, EHEA design remains a huge challenge. Traditional grouping design strategies excessively depend on the reported alloy composition. Meanwhile, the quantitative boundary conditions of grouping strategies remain unclear. This work proposes a grouping strategy via the d-orbit energy level ( ΔMdij) to design EHEAs. The ΔMdij model wa...
