- Abstract
- A unique metal matrix composite (MMC) material with continuously networked TiN was developed to endure immersion in molten steel at far higher temperature (1540 ℃) than the melting temperature (1430 ℃) of matrix AISI 316L stainless steel. In this structure, the reinforcements are continuously interconnected like spider web throughout the material. Even when dipped in molten steel, the material can maintain the shape with enhanced mechanical strength and toughness. During dipping or heat treatment at elevated temperatures, the continuously-networked structure of TiN was significantly strengthened by sintering. The formation of various oxides during dipping or heating was highly helpful to improve the connectivity of TiN, and yields increases in both its strength and toughness. Because of these unique structure and properties, this material may be useful to be the successful candidate to handle molten metallic melts as tapping materials in steelmaking process, and separators in dual-casting molds. © 2021 Elsevier B.V.
