TiB2-TiC Reinforced Martensitic Steel Fabricated by Conventional Solidification

The article explores the fabrication of a TiB2-TiC reinforced martensitic steel using conventional solidification techniques. It highlights the advantages of this material, such as high strength, hardness, and low density, which are crucial for lightweight design in industries like aerospace and automotive. The study presents a unique microstructure with uniformly distributed TiB2 and TiC ceramic particles in a hard martensite matrix, achieved through liquid metallurgy. The mechanical properties of the resulting steel matrix composite (SMC) are investigated, showing attractive tensile properties and hardness values. The research also delves into the solidification process and the sequential precipitation of reinforcements, providing insights into the microstructural features that influence the material's properties. The article concludes with suggestions for further improving the mechanical properties by adjusting the carbon content.
