Abstract

Metal-matrix-composites are produced by the laser particle injection processing route. SiC particles are entrapped during solidification of liquid Ti. Since the injected particles partially dissolve, depending on the process conditions, new phases are formed in the matrix. The degree of dissolution will significantly influence the mechanical performance of the MMC. In particular, the interfacial region between Ti and SiC particles is closely investigated with (high resolution) transmission electron microscopy. Furthermore, hardness indents are performed to examine the crack initiation and the crack propagation behaviour at the interface.
