Microstructure and direct measured micro-strain by TEM of hot iso-static pressed alumina-titanium carbide (Al<inf>2</inf>O<inf>3</inf>-TiC) composite

Alumina-titanium carbide composite (Al2O3-TiC) is one of advance ceramic matrix composites (CMC) that have been used in machining tool and tribology application because of its excellent mechanical properties. Powder processing is often a chosen method to produce this family of material, i.e. hot pre...
