Metal matrix composites (MMCs) are the intimate combination of continuous metal matrix and reinforcing materials [1, 2].MMCs encompass a diverse range of materials that can be classified based on their metallic matrix (e.g. Ti, Al, Mg, Cu, Fe, Ni, Co, etc) and reinforcing materials (e.g. particles, fibers, and whiskers) [3–5].Over the recent decades, MMCs have . However, the service requirements in some applications justifiably allow for employing the composite as a bulk material [2]. In situ particle reinforced aluminium matrix composites have received a . In metal matrix composites based on aluminium, a matrix plays a significant role. Reinforcement is the additional component encompassed within the matrix. Non-metallic reinforcements such as SiC, C, Al 2 O 3 , B, B 4 C, BN, and TiB 2 are commonly used in manufacturing of composites [1] .

Fe–xTiC in situ metal matrix composites (MMCs) are fabricated utilizing a cold crucible inductive melting (CCIM) technique with varying TiC amounts (2, 3.5, and 5 wt%).Steel blocks and pure Ti plates are remelted in a water-cooled copper crucible. The subsequent solidification of [Ti]- and [C]-rich melt yields TiC reinforcement particles in an ingot. Aluminum metal matrix composites (AMMCs) are fascinating because of their low processing temperature, leading to low energy requirements [3].It is the class of materials that had proven successful when low weight, high stiffness and moderate strength were the prerequisite requirement [4].As a result, AMMCs have gradually replaced conventional metal alloys in . In situ TiC particle reinforced titanium matrix composites (TMCs) were successfully fabricated by reactive sintering of Ti + Mo 2 C and Ti + VC compacts. The results of the tensile tests at ambient and elevated temperatures show that the strength of the composites increases with increasing additive content (Mo 2 C and VC), and decreases with increasing temperatures. In this paper, the TiC matrix composites reinforced by SiC and Ti 3 SiC 2 were in-situ fabricated by spark plasma sintering (SPS) at 1400–1600 °C. The degradation of Ti 3 SiC 2 was exploited as a beneficial phenomenon in obtaining high-performance TiC matrix composites, circumventing the poor interfacial bonding between reinforcement and TiC matrix. The effect of .
