Titanium-based metal-matrix composites (MMCs), reinforced with ceramic particles have considerable potential for improvements in properties and service temperature, while retaining isotropic behavior and ease of fabrication using conventional processing methods. Traditionally, titanium MMCs have been produced by such processing techniques as powder metallurgy and casting technologies. In recent years, novel processing techniques based on the in situ production of MMCs have emerged. In the present work, the authors highlight a novel in situ process in which traditional ingot metallurgy plus SHS techniques were used to produce (TiB + TiC)/Ti matrix composites. This article gives particular attention to the reaction principles and reinforcements morphologies.
