Multi-principal element alloys (MPEAs) offer a vast unexplored compositional space near the centers of phase diagrams, but the experimental exploration of this multidimensional space can be challenging. To address this, our recent research has focused on the development of computational algorithms and models for efficient and effective exploration of this space. Our approach aims to develop microstructurally engineered multi-phase MPEAs by understanding the relationships between composition, transformation pathways and microstructure. Through high-throughput CALPHAD thermodynamic modeling and phase-field simulations, complemented by experimental efforts, we identify the critical alloy and processing parameters affecting the microstructure development. Our results illustrate a rich variety of novel two-phase microstructures that could be engineered through various transformation pathways present in MPEAs.
