Heat treatment of additively manufactured Al-Ce based multicomponent alloys leads to complex microstructure evolution. In this research, the ability to extend the phase transformation theories involving nucleation of a product phase from a heterogeneous multi-phase microstructure typical to that of additively manufactured samples is explored. The Al-10Ce-8Mn (wt%) was used as a model alloy system. Under additive manufacturing conditions different solidification microstructures were obtained due to spatial and temporal variations of thermal gradients (G) and liquid-solid interface velocities (R) within a given melt pool. Near the melt pool boundary (high G and low R, referred as MPB region), initially, Al₂₀Mn₂Ce forms from the liquid followed by a eutectic of FCC Al and Al₁₁Ce₃. In the melt pool interiors (low G and high R referred as ES region) a eutectic structure between FCC Al and Al₂₀Mn₂Ce is observed. During subsequent heat treatments, the MPB and ES regions transform into different sets of microstructures. In the MPB region, a fine globular microstructure containing FCC Al, Al₁₁Ce₃, Al₆Mn, and Al₁₂Mn results from the decomposition of Al₂₀Mn₂Ce. In the ES region a faceted Al₅₁Mn₇Ce₄ plate phase results from the decomposition of Al₂₀Mn₂Ce. The formation of the Al₅₁Mn₇Ce₄ phase within the eutectic microstructure at the boundaries of FCC Al and Al₂₀Mn₂Ce has not been reported in the literature. Further, these two distinct phase transformation pathways are rationalized based on the role of driving force on the nucleation of (Al₆Mn) and/or metastable intermetallic (Al₅₁Mn₇Ce₄) phases at the interface of aluminum (FCC) and the non-equilibrium intermetallic (Al₂₀Mn₂Ce) phases.
