Mapping the mechanical properties of cobalt-based stellite alloys manufactured via blending

Stellite alloys have good wear resistance and maintain their strength up to ~ 600°C, making them suitable for various industrial applications like cutting tools combustion engine parts. This investigation was aimed at i) manufacturing new alloy blends using powder metallurgy ii) mathematically mapping hardness, yield strength, ductility impact energy of base blends. Linear, exponential, polynomial approximations dimensional analyses were conducted in this semi-empirical mathematical modelling approach.
