Magnesium-based composite materials play an important role in aerospace and automobile industries because of their low density, stiffness & high specific strength. These hybrid composite materials were needed to increase the strength, surface finish, machinability, corrosion resistance, etc. To address such a problem this work has been focused on the preparation of magnesium-based metal matrix composite materials AZ91C reinforced with the B4C with two different proportions which are prepared by using the casting process. For the characterization of the prepared Mg-based MMCs, various tests like tensile test and hardness test have been performed on three model sample specimens of namely AZ91C(100%)+B4C(0%). AZ91C(98%)+B4C(2%) And AZ91C(96%)+B4C(4%). It was found that the compressive strength is and hardness is decreased due to the addition of the B4C to the matrix alloy AZ91C while tensile strength is increased. The tensile strength is increased by 15.58% with the addition of 4% B4C when compared with 2% of B4C and also hardness is increased by 31.49%. The compressive strength is decreased by 41.43% with the addition of 4% B4C when compared with 2% of B4C.

Currently, metal–matrix composite materials are some of the most promising types of materials, and they combine the advantages of a metal matrix and reinforcing particles/fibres. Within the framework of this article, the high-temperature synthesis of metal–matrix composite materials based on the (Ni-Ti)-TiB2 system was studied. The selected approaches make it possible to obtain composite materials of various compositions without contamination and with a high degree of energy efficiency during production processes. Combustion processes in the samples of a 63.5 wt.% NiB + 36.5 wt.% Ti mixture and the phase composition and structure of the synthesis products were researched. It has been established that the synthesis process in the samples proceeds via the spin combustion mechanism. It has been shown that self-propagating high-temperature synthesis (SHS) powder particles have a composite structure and consist of a Ni-Ti matrix and TiB2 reinforcement inclusions that are uniformly distributed inside it. The inclusion size lies in the range between 0.1 and 4 µm, and the average particle size is 0.57 µm. The obtained metal-matrix composite materials can be used in additive manufacturing technologies as ligatures for heat-resistant alloys, as well as for the synthesis of composites using traditional methods of powder metallurgy.
