High Entropy Alloys as a Bold Step Forward in Alloy Development (Postprint)

reportActive / Technical Report | Accession Number: AD1078689 | Open PDF

Abstract:

Diluting a base element with small amounts of another has served as the basis for developing alloys for thousands of years since the advent of bronze. Today, a fundamentally new idea where alloys have no single dominant element is giving new traction to materials discovery.
