Iron based high entropy alloy containing aluminum is facing a challenge in the liquid-solid transition regime due to its high affinity to segregation. In this research, the segregation of alloying elements in the designed high entropy alloy has been tracked after pouring in special investment mold that possesses different modulus with fluctuated solidification time. Different compositions of the targeted alloy were developed through melting of pure metals in induction furnace. X-ray Fluorescence (XRF), optical microscope, and SEM have been used for monitoring the chemical, and phase constituents among the different regions of solidification. In addition, the mechanical properties of the designed alloy have been determined using uni-axis tensile test, and impact toughness. It was well proved that the solidification time has a significant effect on promoting the characteristic properties of iron based high entropy alloy containing aluminum. Aluminum shows high percentage with increasing the solidification time. In addition, the mechanical observations proved that decreasing the solidification time enhance and improve the mechanical properties.
