Ashby plot of strength vs. density for engineering materials. (Yield strength for metals and polymers, tear strength for elastomers, compressive strength for ceramics, and tensile strength for composites.) The low-density HEA is indicated with the star. Youssef et al. |
Researchers from North Carolina State University and Qatar University have developed a new high-entropy alloy that has a higher strength-to-weight ratio that they say is unmatched by any other metallic material.
