Refractory high-entropy alloys (RHEAs), comprising group IV (Ti, Zr, Hf), V (V, Nb, Ta), and VI (Cr, Mo, W) refractory elements, can be potentially new generation high-temperature materials. However, most existing RHEAs lack room-temperature ductility, similar to conventional metals alloys. Here, we propose an alloy design strategy intrinsically ductilize based on the electron theory more specifically decrease number of valence electrons through controlled alloying. A ductile RHEA,...
The Hf0.5Nb0.5Ta0.5Ti1.5Zr refractory high-entropy alloy with excellent corrosion resistance in the 3.5 wt% NaCl solution is identified this work. This exhibits much better general than that of 316L stainless steel, due to its current density being about one fifth latter. Meanwhile, pitting potential reaches an unusually high value +8.36 V, higher reported alloys. superior passivity accredited formation a single-phase solid containing amount homogenously distributed passivity-promoting...
Thermoelectric (TE) generators that efficiently recycle a large portion of waste heat will be an important complementary energy technology in the future. While many efficient TE materials exist lower temperature region, few are at high temperatures. Here, we present properties high-entropy alloys (HEAs), as potential new class materials. We show their can controlled significantly by changing valence electron concentration (VEC) system with appropriate substitutional elements. Both electrical...
Abstract Chemical and topological parameters have been widely used for predicting the phase selection in high-entropy alloys (HEAs). Nevertheless, previous studies could be faulted due to small number of available data points, negligence kinetic effects, insensitivity compositional changes. Here this work, 92 TiZrHfM, TiZrHfMM, TiZrHfMMM (M = Fe, Cr, V, Nb, Al, Ag, Cu, Ni) HEAs were prepared by melt spinning, build a reliable sufficiently large material database inspect robustness previously...
Abstract Developing a highly stable and dendrite‐free zinc (Zn) anode is crucial for the commercial application of aqueous Zn‐ion batteries. Herein, dual‐functional layer interface constructed on Zn surface via femtosecond laser processing strategy, effect periodic micro–nano structures accelerating transport dynamics ions suppressing dendrite growth investigated. The oxide exhibits strong affinity low diffusion barrier ions, significantly inhibiting corrosion side reactions. Meanwhile,...
The influences of Cu additions on the microstructural evolution and room-temperature tensile properties as-cast CrFeCoNi were investigated in detail. results revealed that structure alloy changed from a FCC single-phase to FCC1 plus FCC2 dual-phase by adding element. phase was determined be Cu-rich existing inter-dendrite region, its volume fraction increased with increase additions. formation mainly ascribed liquid-phase separation induced large positive mixing enthalpy between other...
Cu-Fe alloys are expected to be extensively used in electronics, transportation and machinery industries due the extraordinary mechanical properties functional properties. To optimize rolling process final of plates. The effect path, temperature thickness reduction on microstructure evolution, electrical alloy carefully investigated. results shown that has a significant alloy. yield strength plates with 20% is more than 2 times higher homogenized ingot. While increases gradually as further...
Designing alloys with an accurate temperature-independent electrical response over a wide temperature range, specifically low coefficient of resistance (TCR), remains big challenge from material design point view. More than century after their discovery, Constantan (Cu-Ni) and Manganin (Cu-Mn-Ni) remain the top choice for strain gauge applications high-quality resistors up to 473-573 K. Here, average TCR is demonstrated that ≈800 times smaller in range 5-300 K >800 any these standard...
