Micromechanics and character of destruction of metallic composite materials

The basic principles of the strengthening mechanism and brittle failure of metal - based composite materials reinforced by a) dispersed particles, b) brittle and plastic wires are introduced. The failure types and parameters affecting the ultimate strength at tension, and the theory of strength according to the observed type of destruction are revealed. As an effective method for producing metal composite materials, the technologies of hot extrusion providing a uniform plastic deformation of the reinforcing phase, and therefore, 100 percent implementation of its strength properties for enhancing the mechanical properties of the composite material are introduced
