Accelerated exploration of multi-principal element alloys with solid solution phases
TL;DR: A new approach is developed to rapidly assess structural metals by combining calculated phase diagrams with simple rules based on the phases present, their transformation temperatures and useful microstructures, finding the surprising result that solid solution alloys become less likely as the number of alloy elements increases.
