To overcome some of the inherent problems that are associated with conventional
processes, several in situ methods have been developed to obtain metal/ceramic composite
materials. In this paper recently developed processes have been reviewed with a greater
emphasis on directed melt oxidation and nitridation. These methods offer microstructures
with varying metal/ceramic combinations. In some processes, metal matrix composites
dispersed with controlled quantities of ceramic phase (s) are possible whereas in other …

… This paper reviews the obtaining processes of composite materials with a greater
emphasis on nitriding and oxidation by directed melting. These obtaining methods provide
microstructures with different combinations of metal–ceramic. Metal matrix composites with
controlled amounts of dispersed ceramic particles are obtained by "in situ" processes. The …
