    Abstract: A ceramic composite (10) comprises a transient plastic phase (12) and a reactant phase (14). The transient plastic phase (12) includes a metallic component and may also include a non-metallic component. Heat and pressure are applied to the ceramic composite (10) to plastically deform the transient plastic phase (12) of the composite (10) and densify the composite (10). The densified composite is heated to react the transient plastic phase (12) and the reactant phase (14) in the solid state at a reaction temperature lower than the melting temperature of either the transient plastic phase (12) or the reactant phase (14). A portion of the metallic component of the transient plastic phase (12) is transferred to a reinforcing phase (22) whereby a strengthened and toughened ceramic composite is formed comprising: (1) a matrix phase (20); and (2) a reinforcing phase (22) in the matrix phase (20).
