HEAS Data Platform
Derived from the Materials Project at Lawrence Berkeley National Laboratory, providing structured data on high-entropy alloys, traditional materials, and elastic properties.
Data Collections
Three datasets covering high-entropy alloys, traditional materials, and elastic properties
High-Entropy Alloys Database
High-Entropy Alloys structured data · elastic / electronic / magnetic properties · CIF crystal structures
Traditional Materials Database
Traditional Materials complete properties · energy / stability analysis · full crystal-system coverage
Elasticity Database
Elastic Materials constants · anisotropy · Debye temperature / sound velocity · full moduli
Quick Start
Three steps to the complete data of any target material
Search Materials
Enter a chemical formula (e.g. FeNi) or MP-ID (e.g. mp-2866) in the search box; fuzzy matching and element-combination filtering are supported.
Filter by Dimensions
Filter precisely by crystal system, space group, formation-energy range, stability, and elemental composition to pinpoint the target material.
Inspect Details
View elastic constants, electronic band gaps, and magnetic parameters, or analyze crystal structures and diffraction via CIF / XRD.
