**Matrix phase of MMC**

In metal matrix composite matrix phase is the continuous phase of metal which holds or grips the reinforcement of the composite materials together, allows the fabrication into desired shapes and further, helps to transfers the load form matrix to reinforcement and vice versa. The most common metals matrices are aluminum, magnesium, and copper etc. or their alloys. The sintering temperature of metal matrix composites during the composite fabrication depends on the matrix of the composite materials.

Metal Matrix Composites (MMCs) typically undergo different phases during their fabrication and processing. The matrix phase of an MMC refers to the metallic material that forms the bulk of the composite structure and surrounds the reinforcement material.

The matrix phase in MMCs can be a variety of metals or alloys, depending on the specific application requirements. Common matrix materials include aluminum, titanium, magnesium, copper, and nickel. These metals are chosen for their desirable properties such as strength, thermal conductivity, corrosion resistance, or other specific characteristics.

The matrix phase of an MMC acts as a continuous phase that provides mechanical support, thermal conductivity, and other functional properties to the composite. It is responsible for transferring loads between the reinforcement materials, enhancing the composite’s mechanical strength and toughness.

To form the MMC, the matrix material is typically processed into a molten state, and the reinforcement material, such as ceramic particles, fibers, or whiskers, is added and distributed within the matrix. Subsequently, the mixture is solidified or processed further through methods like casting, powder metallurgy, or other advanced manufacturing techniques.

During the processing of MMCs, the matrix phase can undergo various treatments or modifications to improve its compatibility with the reinforcement material and enhance the overall composite properties. These treatments may include surface modification, alloying, heat treatment, or the addition of grain refiners or strengthening agents.

Overall, the matrix phase of an MMC plays a crucial role in determining the composite’s mechanical, thermal, and other functional properties. The choice of matrix material and its processing parameters greatly influences the final characteristics of the composite.
