High-entropy alloys (HEAs), which are composed of random atomic-scale mixtures of elements from transition metals, have simple crystal structures, though the metals are arranged randomly on the lattice points, giving each alloy the properties of a both a glass and a crystalline material. Scientists from the CAS Institute of Physics and the Chemistry Department at Princeton University have found a HEA composed of tantalum (Ta), niobium (Nb), hafnium (Hf), zirconium (Zr), and titanium (Ti) which superconducts continuously from low to high pressures, making it a promising candidate for new applications of superconductors under extreme conditions.
