Multi-principal element alloys (MPEAs) are promising for demanding mechanical, thermal, corrosion and wear environments. Improved understandings of microstructural evolution with processing and deformation are prerequisite for the adoption of MPEAs in structural applications. Recrystallization, grain growth and precipitation kinetics are of particular relevance. In order to study these behaviors, a family of non-equiatomic, Fe-rich and Co-free precipitation-hardening MPEAs was designed through a multifactor screening approach. A design of experiment for thermomechanical processing and precipitation heat treatments is presented. Recrystallization, grain growth and precipitation kinetics are discussed and compared to existing ferrous alloy products.
