Summary:Nickel-Iron based superalloy (43Ni-14Cr, wt%) is used as high temperature material in space based transportation systems. It retains its high strength (>100 MPa) upto 800°C alongwith good cryogenic properties, hot corrosion resistance and phase stability at elevated temperatures. The alloy was melted in vacuum induction melting furnace and was refined through vacuum arc refining process. Hot working and heat treatment of the alloy was carried out and the material was characterized for its mechanical properties at different temperatures. Microstructural analysis was conducted at different stages of processing in order to optimize the processing parameters. This paper brings out the work carried out on the process development for this alloy.
