**Abstract Scope** |
The material-design strategy of combining multiple elements in near-equimolar ratios has spearheaded the emergence of high-entropy alloys (HEAs), an exciting class of materials with exceptional engineering properties. Elastic properties are important criteria for engineering material design. The elastic tensor of a material provides a complete description of the response of the material to external stresses in the elastic limit, which provides fundamental insight into the nature of bonding in the material, and is known to correlate with many mechanical properties. We employed an integrated first-principles and experimental approach to study the elastic properties of refractory high entropy alloys, an exciting class of materials with exceptional engineering properties. A statistical learning model of elastic constants will be assessed for the refractory HEA systems. The effects of HEA compositions on the elastic properties and phase stability will be discussed. |
