Abstract Scope AISI 316L stainless steel reinforced with networked TiN was developed to enhance its endurance at elevated temperature. The composite material was fabricated by mixing the powders of constituents, followed by heat treatment and rolling to reduce voids. The fabricated composite was successfully reinforced by TiN mainly because of its unique 3D networked morphology which is obviously distinguished from common particle-like or fiber-like reinforcing materials. This structure was formed by separation of powders due to its larger size difference. This composite material maintains its shape in the molten steel up to 70℃ above the melting point of the matrix thanks to 3D network structure of TiN which acting as a reservoir of the matrix. Furthermore, we studied how the matrix and 3D network structure of this material changes by various kinds of heat treatments. Finally, the mechanical properties of materials measured by the bending and the hardness tests were thoroughly analyzed.
