| Abstract Scope |
Most modern toughening concepts for ceramics are based on the incorporation of a second phase into the ceramic matrix. A three dimensional interpenetrating phase composites (IPCs), whose architecture consists of a continuous matrix network penetrated by a continuous reinforcement network, can yield truly remarkable properties owing to their microstructure stability and enhanced fracture resistance. The most common way of producing IPCs is infiltration of liquid metal into a porous ceramic perform. In in-situ IPCs, the ceramic and metal networks are generated by thermodynamically feasible reactions and are often arranged as interpenetrating networks. For example, thermite reaction between volatile oxides and metallic elements (Al, Ti etc) generates networks of Al2O3, MgAl2O4 interpenetrated with Al-Si, Al-Mg2Si, TiAl alloy composites. The research was focussed on the development of in-situ Al-Al2O3 IPCs using recyclable silica sources and their physical and mechanical property responses at various conditions.
