چکیده
Abstract This study reports the structure and mechanical properties of new refractory Ti 37.5 Nb 12.5 Hf 25 Al , 40 30 15 20 Ta 10 (at.%) high entropy alloys. After annealing at 1200 °C for 24 h, program alloys had a single-phase B2 structure. Further 600 h resulted in formation Widmanstatten orthorhombic particles (O-phase) bcc matrix. The annealed T = showed moderate strength good ductility (>50%) 22 °C; while alloy was stronger, but less ductile both temperatures. Subsequent significantly increased °C, maintaining compressive sufficient room-temperature.

Phase Equilibria in Prototype Nb-Pd-Hf-Al Alloys
The phase equilibria in two prototype alloys with nominal compositions 60Nb-20Pd-10Hf-10Al and 40Nb-30Pd-15Hf-15Al (in at. pct) are investigated using scanning electron microscopy and X-ray diffraction. The alloys were heat treated at 1200 °C and 1500 °C for 200 hours each. The phase analysis revealed that the alloys were, for the most part, in the three-phase equilibrium between (Nb), Pd2HfAl,...
متن کاملFirst-principles calculation of phase equilibrium of V-Nb, V-Ta, and Nb-Ta alloys
In this paper, we report the calculated phase diagrams of V-Nb, V-Ta, and Nb-Ta alloys computed by combining the total energies of 40–50 configurations for each system (obtained using density functional theory) with the cluster expansion and Monte Carlo techniques. For V-Nb alloys, the phase diagram computed with conventional cluster expansion shows a miscibility gap with consolute temperature ...
متن کاملEffect of electron count and chemical complexity in the Ta-Nb-Hf-Zr-Ti high-entropy alloy superconductor.
High-entropy alloys are made from random mixtures of principal elements on simple lattices, stabilized by a high mixing entropy. The recently discovered body-centered cubic (BCC) Ta-Nb-Hf-Zr-Ti high-entropy alloy superconductor appears to display properties of both simple crystalline intermetallics and amorphous materials; e.g., it has a well-defined superconducting transition along with an exc...
متن کاملTemperature Effects on the Tensile Properties of Precipitation-Hardened Al-Mg-Cu-Si Alloys
Because the mechanical performance of precipitation-hardened alloys can be significantly altered with temperature changes, understanding and predicting the effects of temperatures on various mechanical properties for these alloys are important. In the present work, an analytical model has been developed to predict the elastic modulus, the yield stress, the failure stress, and the failure strain...
متن کاملPrecipitation behavior of AlxCoCrFeNi high entropy alloys under ion irradiation
Materials performance is central to the satisfactory operation of current and future nuclear energy systems due to the severe irradiation environment in reactors. Searching for structural materials with excellent irradiation tolerance is crucial for developing the next generation nuclear reactors.
