| Abstract Scope |
Structural materials with low densities and good mechanical properties have been sought after for many years. The new paradigm in alloy development/materials science of multi-principal element alloys offers greatly expanded possibilities for development of such alloys. For the purposes of this talk, “low density” will be defined as densities equal or less than about 6.0 g/cc. That is, for densities less than those of light weight steels and more comparable to commercial Ti or Al alloys. The limited number of studies from the literature on low density high entropy alloys will be briefly reviewed. A high throughput computational and experimental study directed by Intermolecular Inc. will be presented. Our group developed a fascinating alloy, Al20Li20Mg10Sc20Ti30 , which was prepared by ball milling of powders. The as-milled alloy exhibited a single phase fcc structure and had a remarkable hardness of about 6 GPa. This alloy will be discussed in some detail. |
