Some features of the fiber-matrix reaction occurring during the manufacture of an aluminum-boron composite material

The reaction of the components in the Al-B system may commence at the boundaries of matrix alloy grains emerging to the foil surfaces. In the formation of the matrix-fiber reaction zone during the pressing of the FCM a key role is played by plastic deformation of the foil, which leads to rupture of the surface oxide films along the grain boundaries of the matrix alloy. A physicochemical reaction resulting in the formation of intermetallic compound phases can be induced by plastic deformation of the aluminum foil at low temperatures. The relative size of the reaction zone in the A1-B system can be controlled by varying the grain size of its matrix.
