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 A series of novel B2-ordered Ti2ZrHf0.5VNb0.5Alx refractory high-entropy alloys (RHEAs) was designed and prepared by vacuum arc-melting. The effect of Al alloying on the microstructure, mechanical properties, and oxidation properties was investigated. The Al addition triggers the transformation of the crystal structure from disordered BCC phase to ordered B2 phase, and the Al1 alloy present single B2 phase structure. This B2 ordering results in significant yield strength incre...

Abstract Cu6Sn5 and Cu3Sn are important intermetallic compounds, greatly influencing the reliability of the Sn-Cu solder system. Micro-alloying Ni has been proved to be effective in suppressing Cu3Sn, but its influence on the formation of Cu6Sn5 is still unclear. In this paper, the nucleation and growth behavior of Cu6Sn5 in Sn-8.5Cu-xNi (x = 0, 0.05, 0.1, 0.5, 1) alloys are in situ investigated using synchrotron X-ray radiography, X-ray diffraction, and electron probe micro-analyzer. The result...

Abstract Tribological behavior of the model AlCoCrFeNi2.1 eutectic high-entropy alloy (EHEA) sliding against different counterfaces including Al2O3, Si3N4, SiC ceramics and GCr15 steel at room temperature (RT), and particularly SiC at elevated temperatures were investigated. Our EHEA was found to maintain high hardness (>197 HV) up to 900 °C. The RT tribology tests show that the friction and wear of the EHEA are slightest when against SiC. The wear rates of the EHEA increases monotonously from R...

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 ...

A series of AlxCrFe2Ni2Mo0.2 alloy consisting of FCC + BCC phases have been designed, and their as-cast microstructures and mechanical properties were also investigated with x ranging from 0.6 to 0.9. It was found that with the addition of Al element, the solidified structures changed from dendrite to columnar crystal then back to dendrite again. Moreover, the increased amount of BCC phase resulted in finer and more uniform microstructures of FCC [FeCrNi(Mo)] and BCC (Al–Ni) phases. Tensile yiel...

CoCrFeNi2V0.5Tix high entropy alloy coatings were synthesized by laser cladding on Ti-6Al-4V (annotated as TC4) substrate. The microstructures, hardness, and wear properties of the coatings were studied in detail. The results showed that these coatings were all composed of body-centered cubic (BCC) solid solution, (Co,Ni)Ti2 phase, and Ti-rich phase. With the increase of Ti content (x in the range of 0–1.0), the hardness of these coatings (about 960 HV) was basically unchanged and stabilized, wh...

Abstract In situ synchrotron X-ray radiography is used to study the effect of pulse current on the nucleation and growth of (Cu, Ni)6Sn5 intermetallic compounds (IMCs) during the solidification of Sn–10Cu–1Ni (wt.%) alloy. The synchrotron tomography analysis reveals that the (Cu, Ni)6Sn5 exhibits a six-fold snowflake-like 3D morphology. As the density of pulse current increases from 0 to 200 A/cm2, (Cu, Ni)6Sn5 gradually exhibits a direction-dependent morphology and the “self-poisoning” phenomen...

The AlCrFeNi2W0.2Nbx high-entropy alloy (HEA) coatings were synthesized on the 304 stainless steel by laser cladding. The microstructure, microhardness and wear resistance of HEA coatings were investigated. The HEA coatings show a good metallurgical bonding to the substrate, and they consist of the cladding zone, bonding zone and heat-affected zone. The phase structures of the HEA coatings are the BCC solid solution phase and the Fe2Nb-type Laves phase. The Nb0.5 composition shows a hypo-eutecti...
