The present investigation reports the formation and stability of multi-component AB2-type Laves phase in Ti–Zr–Ni (V, Cr, Fe, Mn, Co)ternary to octonary alloys system. To probe the formation and stability of AB2-type Laves phase in high-entropy alloys, a series of multi-component alloys...
Laves phasePhase predictionIn this study, we have analysed Laves-phase formation in high-entropy alloys (HEAs). For that purpose, the AlCrxNbTiV and AlxCrNbTiVZr (x = 0, 0.5, 1, 1.5) alloys were produced and examined. It was found that the AlNbTiV and AlCr0.5NbTiV alloys had ...
[2] first reported high entropy alloy (HEA) as a type of novel structure material that demonstrated superior properties to those of conventional alloys. The HEAs have exceptional mechanical properties, such as strength, hardness, high temperature phase stability, improved wear, corrosion, and ...

The conditions for the formation of Laves phases of type C14 were established based on the results of studies of a number of high-entropy alloys (HEA). The influence of the electron concentration of chemical elements on its content, as well as the hardness and modulus of elasticity of hard-...
phase always coherently precipitates from Nbss and thus strengthen it. Moreover, addition of Cr would promote formation of Laves phase, such as Cr2Nb precipitates [17]. Silicides and Laves phases precipitates might improve the oxidation resistance and creep property of Nb-Ti-Si based alloys ...
The refractory high-entropy alloys (RHEAs) have been the subject of considerable research in recent years. Since the Laves phase usually leads to a dramatic decrease in the malleability of RHEAs at ambient temperatures, it is critical to identifying the Laves-phase formation. Here, a facile and...
