Abstract: WC-65Mn metal matrix composites was produced by the IMS (incremental melting and solidification)process in order to research and develop a process making metal matrix composites. The processing parameters of IMS, including power supply and mould velocity of movement etc, were researched.The microstructure was observed by SEM and the distribuions of WC particles were quanficationally measured with the aid of IMAGE TOOL soft, and at the same time the mechanical propertes were tested. The results showed that the distributions of WC particles were uniformity, in addition, the bend strength and degree of hardness were all good at the condition of suitable power supply and favorable mould velocity.IMS process can be a method to produce metal matrix composites.
