Metal matrix composite may be one of the most attractive engineering materials in 21 st century. More attention is paid to short fiber and ceramic particulate reinforced metal matrix composites. Aluminum alloys and magnesium alloys are the best candidates for matrix

while ceramic particulate is in the investigator’s good graces due to its excellent properties. Addition of reinforcement in metal matrix could lead to the increase of strength

modulus

hardness and wear resistance

the improvement of the performances at elevated temperature and fatigue strength

and the decrease of the coefficient of thermal expansion

but to the decrease of ductility and toughness. Over the last two decades

a variety of techniques has been evolved in an attempt to successfully manufacturing particulate reinforced metal matrix composites （PRMMCs） and to optimizing the microstructure and mechanical properties. Accordingly

the process can be classified into three categories: （1） liquidphase process

（2） solidphase process and （3） twophase process. The interfacial chemical reaction between metal matrix and reinforcement depends upon many factors

such as fabrication process

composition of matrix and reinforcement

temperature and time. On the other hand

it shows a great influence on the fabrication process and the properties of composites. It is one of the most important task of investigations to understand and control the interfacial reaction in order to make it favorable to the processing and properties of PRMMCs. Discussion of techniques and interfacial reaction and control in PRMMCs is focused on present paper.
