Traditional alloys are designed on the basis of one or more majority of materials which is Fe-based, Ni-based, and Co-based super alloy for mechanical properties enhancement but results with poor ductility at room temperature. New alloy design of materials requires more alloying elements for improving the material properties consistently. High entropy alloy consists of at least five principal elements with the concentration of each material between 5 at% and 35 at% on the basis of maximum configurational entropy at equi-atomic composition with more stable than intermetallic at elevated temperatures. In this paper, FeCrNbVMn alloy phase formed by mechanical alloying. The mechanically alloyed powders were subsequently consolidated by cold pressing and sintered in tube furnace. Analysis of microstructure and mechanical properties were carried out with the help of XRD, SEM, TEM and nanoindetation tests. The bulk sample showed hardness of 19 GPa at nano scale.
