B 4C particles reinforced aluminium matrix composites were successfully fabricated by traditional powder metallurgy(CPM) and high energy ball milling powder metallurgy(HEBM PM) respectively. The characteristics and forming mechanism of B 4C particle distribution and interfacial bonding and the effect of particle distribution and interfacial bonding on the HEBM PM composites were investigated. Test results indicated that, the yield and ultimate tensile strength of 17vol% B 4C p/6061Al composites fabricated by the HEBM PM were 415 MPa and 470 MPa, increased by a factor of 69% and 70% respectively compared with that of 17vol% B 4C p/6061Al composites fabricated by the CPM. Microstructural analysis showed that, spatial distribution of B 4C particles in composites made by the HEBM PM was uniform, and there was an interface zone between B 4C particles and Al matrix, which was composed of superfine Al grains in ordered banding distribution and particle like substances of nano metre size. The chief mechanism of particle even distribution is that aluminium particles form a cold weldings zone on steel balls and B 4C was squeezed into cold welding zone constantly during the high energy ball milling process. Forming an interfacial bonding between B 4C particles embedded in matrix and aluminium with fresh surface during the milling is an important requirement for obtaining composites with good interfacial bonding.
