Breakthrough in superalloy bi-metallic structures through additive manufacturing can reduce import of super-alloys
Advancements in Additive Manufacturing for Superalloy Structures

A crack-free bi-metallic structure developed by researchers using a technique called laser-based powder bed fusion (PBF-LB/M) additive manufacturing can help in reducing the overall use of expensive superalloys thereby reducing the import dependency.
Stainless steels and nickel-based super alloys are widely used in aerospace, nuclear, as well as thermal power plants.
Certain regions of a gas turbine may experience temperatures as high as 2000°C, while adjacent sections are exposed to lower temperatures during service conditions.
The development of bi-metallic structures through additive manufacturing is crucial for India's ambition to decrease reliance on imported superalloys, enhancing domestic capabilities in critical sectors.
