Refractory high-entropy ceramics are attractive for use in extreme environments. Here, non-equimolar refractory metal high-entropy nitrides exhibit 6.9 GPa strength at 1000 °C during micromechanical ...
A subzero ice recrystallization route creates multimetal high entropy aerogels and coatings with uniform element mixing, offering a low temperature path to porous macroscopic alloy structures.
