Fe-36Ni-12Cr-3Ti-1Al alloy is a precipitation hardenable alloy and was developed for use as elastic and sensitive elements of high precision measuring instruments. Due to its superior elastic properties, this alloy has been successfully used in the manufacturing of springs and elastic-sensitive elements. It has good compatibility with liquid oxygen (LOX), and is resistant to aggressive or acidic environments. This alloy was indigenized in the form of cold drawn wires. Cold drawn wires were subjected to nine different combinations of solution treatment and aging (STA) to identify the desired heat treatment process to achieve balanced mechanical properties. Mechanical and metallurgical characteristics of all these conditions were analyzed. Out of this these nine combinations, cold drawing followed by aging at 670 °C-4 h, showed higher strength meeting required ductility. This study helped in developing heat treatment process and spring coiling combination to achieve desired stiffness, strength, and ductility.
