Microstructures, phase stability and properties of the as-solidified CoCrCu0.5FeNi(Si/B)x alloys were studied in this work. Intermetallic compounds are found when Si or B was added in a FCC structural CoCrCu0.5FeNi high-entropy alloy, and B possess a better intermetallic formation ability than Si. On the other, solute ability of Si is better than that of B in CoCrCu0.5FeNi alloy. The strength of CoCrCu0.5FeNi high-entropy alloy was improved after the addition of Si and B, and the strengthen mechanism was discussed. Moreover, parameter g can provide a reference to predict the ability of forming intermetallic compounds in CoCrCu0.5FeNi(Si/B)x alloys. The increase of δ is prone to the forming of intermetallic compounds. But the volume fraction of intermetallic compounds increase with the decrease of Ω in the same alloy system.

A series of CoFeNi2W0.5Tax (x = 0-0.6) high entropy alloys (HEAs) were synthesized by arc melting to investigate the alloying effect of Ta element on the microstructure and mechanical properties of the CoFeNi2W0.5 alloy system. Phase constitution, microstructure and mechanical properties of the alloys were analyzed by X-ray diffraction (XRD), scanning electron microscopes (SEM), Vickers hardness and compressive test. It was found that when x = 0, the alloy consists of a single-phase face-centered cubic (FCC) solid solution structure and exhibit excellent ductility, the compressive plastic elongation of which can reach 80% without fracture. While with increasing Ta content, the brittle Co2Ta-type Laves phase appears which leads to a decrease of the plastic strain and an increase of the yield strength, and the Vickers hardness shows an obvious increase from HV 179.5 to HV 753.2.
