In the present investigation, efforts were made to fabricate non-equiatomic Fe-Mn-Ni-Cr-Co-Al-Ti septenary Fe based high-entropy alloy (HEA). The Fe based HEA was fabricated using vacuum induction melting in a magnesia crucible and as-cast into a plate of 2.5 kg. The phase evolution, chemical composition and thermal stability of these alloy were established through X-Ray diffraction (XRD), Transmission electron microscopy (TEM), Scanning electron microscopy and Differential scanning calorimetry (DSC) respectively. The objective of this work is to study the precipitation of the L12 type phase (Ni3(Al, Ti)) in the Fe based HEA matrix. Furthermore, efforts were made to study the mechanical properties of these by using instrumented indentation technique and tensile testing. The current work is a good attempt towards the exploration of Fe-based HEAs to find their scope in structural applications.
