Complex Concentrated Alloys (CCA’s) have the potential to couple concentrated solid solution matrix and intermetallic precipitation leading to both, precipitation strengthening as well as composite strengthening effects. Novel microstructures can be engineered in FCC based CCA’s by controlling the competition between L12 and B2/L21 phases. A wide range of mechanical properties can be obtained by tuning this competition via thermomechanical processing. FCC based CCAs have been designed using the CALPHAD approach to exploit this opportunity. The alloys were produced by conventional arc melting and thermo-mechanically processed to produce microstructures with different volume fractions of L12 and B2/L21 phases. Detailed microscopy using transmission electron microscopy (TEM) and atom probe tomography (APT) was carried out to characterize the alloy in various conditions. Mechanical properties of the conditions were characterized with room temperature tensile testing and microhardness.
