A database of mechanical properties for multi principal element alloys

Multi-principal element alloys (MPEAs) have emerged as a promising class of materials due to their exceptional mechanical properties. In this paper, we present a comprehensive database of mechanical properties for MPEAs – based upon reported works to date. The database encompasses a range of properties, including yield strength, ultimate tensile strength and elongation (from tensile testing); and compressive strength and plasticity (from compression testing). The database incorporates a consolidation of valuable information, including alloy composition, hardness, phases present, processing, and heat treatment conditions. The inclusion of such information allows researchers to correlate mechanical properties with alloy composition and processing parameters, aiding in the digital design of MPEAs with tailored mechanical performance.
