Microstructure and Mechanical Properties of Spark Plasma-Sintered Graphene-Reinforced Inconel 738 Low Carbon Superalloy

The effects of the addition of different percentage compositions of graphene nanoplatelets (GNPs) to a nickel-based superalloy were investigated in this study. A spark plasma sintering (SPS) method was employed in the development of the nickel-based alloy/composites, and the developed bulk nickel-based alloy and its composites were from high-purity micron-size powder. Subsequently, the microstructure and mechanical properties (i.e.,...
