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...

In the present study, a series of AlCoCrxFeNi2.1 (x = 0, 0.25, 0.5, 0.75, 1.0) eutectic high entropy alloys (EHEAs) have been designed and prepared. And the effect of Cr content on the microstructures and mechanical properties of the AlCoCrxFeNi2.1 alloys was systematically investigated. The results indicate that the AlCoCrxFeNi2.1 (x > 0) alloys exhibit almost complete lamellar eutectic microstructures with a mixture structure of FCC and B2 phases. And the AlCoFeNi2.1 alloy without Cr element e...

Abstract Eutectic high-entropy alloys (EHEAs) have drawn extensive attention due to their excellent castability and remarkable combination of strength and plasticity. In this study, a new Fe2Ni2CrMox (x = 0.25, 0.50, 0.75, 1.0, 1.25, 1.50) EHEA family was designed and prepared, with the dependence of microstructural and mechanical evolution on the Mo addition investigated. As the increase of Mo addition in the Fe2Ni2CrMox EHEA, the microstructure evolves from hypoeutectic (x = 0.25) to near-eute...

Abstract In this study, a new Al0.9CoFeNi2 eutectic high entropy alloy (EHEA) was designed, and the microstructures as well as the deformation behavior were investigated. The bulk cast Al0.9CoFeNi2 EHEA exhibited an order face-centered cubic FCC (L12) and an order body-centered cubic (B2) dual-phase lamellar eutectic microstructure. The volume fractions of FCC (L12) and B2 phases are measured to be 60 % and 40 %, respectively. The combination of the soft and ductile FCC (L12) phase together with...

Abstract Ocean engineering equipment frequently undergoes tribological impacts during service, resulting in an accelerated deterioration of ocean materials. Thus an effective strategy by introducing high entropy alloy coating was proposed to protect ocean engineering equipment. Accordingly, a new wear-resistant AlCrFe2Ni2W0.2Mo0.75 high entropy alloy coating was designed and deposited on Q235 steel by laser cladding. The corresponding microstructure, microhardness and tribological properties in ...

We designed a novel Co-free AlCrFe2Ni2Ti0.5 high-entropy alloy (HEA) that features an excellent combination of strength and ductility in this study. The as-cast AlCrFe2Ni2Ti0.5 alloy showed equiaxed grains undergoing spinodal decomposition, which consisted of ultrafine-grained laminated body-centered cubic (bcc) phases and an ordered body-centered cubic (b2) phase, and some precipitates embedded in the b2 matrix. The bcc and b2 phases also feature a coherent interface. This unique structure impe...

Abstract Eutectic high-entropy alloys (EHEAs), as a sub-group of high-entropy alloys (HEAs), are becoming a new research hotspot in the metallic materials community because of their excellent castability, fine and uniform microstructures even in the as-cast state, high strength, and good ductility. Some of the EHEAs have shown promising potentials for industrial applications. Here, the history, interesting solidification microstructure and mechanical properties, and the design strategy of EHEAs ...

This study aimed to investigate the microstructure and mechanical properties of TixZrVNb (x = 1, 1.5, 2) refractory high-entropy alloys at room and elevated temperatures. The TiZrVNb alloy consisted of the body-centered cubic (bcc) matrix with a small amount of V2Zr phase. The Ti1.5ZrVNb and Ti2ZrVNb alloys exhibited a single-phase bcc structure. At room temperature, the tensile ductility of the as-cast alloys increased from 3.5% to 12.3% with the increase in the Ti content. The TixZrVNb alloys ...

CrFeNi2V0.5Wx (x = 0, 0.25) alloys based on these parameters of mixing enthalpy (ΔHmix), mixing entropy (ΔSmix), atomic radius difference (δ), valance electron concentration, and electronegativity difference(Δχ) were designed and prepared. The microstructure and room-temperature mechanical behavior of both alloys were investigated. Compressive test results showed that the CrFeNi2V0.5W0.25 alloy had higher yield strength than that of the W-free CrFeNi2V0.5 alloy, although they all exhibited quite...

A series of Ti2ZrHf0.5VNbx (x = 0, 0.25, 0.5, 0.75 and 1.0) refractory high-entropy alloys were prepared to investigate the alloying effect of Nb on the microstructures and mechanical properties. All the alloys displayed a simple BCC structure. The microstructures of the alloys changed from the initial single-phase columnar structure (x = 0) to dendrite microstructure (x > 0). At room temperature, all the alloys exhibited high ductility (with the compressive strains of more than 50%). With the i...
