Refractory high-entropy alloys

Intermetallics, 2010
Abstract Two refractory high-entropy alloys with near-equiatomic concentrations, W–Nb–Mo–Ta and W–Nb–Mo–Ta–V, were produced by vacuum arc melting. Despite containing many constituents both alloys have a single-phase body-centered cubic (BCC) structure.

New structure in refractory high-entropy alloys

Materials Letters, 2014
Abstract The microstructure of a new refractory high-entropy alloy of composition close to Ti 35 Zr 27.5 Hf 27.5 Nb 5 Ta 5 prepared by arc melting and induction techniques was investigated using X-Ray diffraction (XRD) and transmission electron microscopy (TEM).

Strengthening mechanisms in CrMoNbTiW refractory high entropy alloy

Materials Science and Engineering: A, 2021
Abstract We have investigated the strengthening mechanisms of as-cast CrMoNbTiW BCC refractory high entropy alloy (RHEA). The cast RHEA was deformed at a constant strain rate of 10−3 s−1 and a temperature range of 1100–1300 °C. The various factors contributing to the overall strength of the cast alloy are explored with comprehensive experimental ...

WEDM machining of MoNbTaTiZr refractory high entropy alloy

CIRP Journal of Manufacturing Science and Technology, 2022
Refractory high entropy alloys (RHEAs) have shown great promise for a multitude of advanced engineering applications due to their high mechanical stability from cryogenic temperatures to 1600 °C. However, the low ductility they exhibit at room temperature limits their machinability when traditional machining techniques are used.

Thermodynamic properties of refractory high entropy alloys

Journal of Alloys and Compounds, 2016
Abstract As the potential radiation damage-tolerant materials, Hf Nb Ta Ti Zr high entropy alloys (HEAs) attract considerable attention, whereas the thermodynamic parameters are very limited at different temperatures and under high pressure. In this work we combine the ab initio calculations of supercell with the quasi-harmonic Debye-Gruneisen ...
