The characteristics and process route of electron beam rapid manufacturing technology are introduced. When it is applied in the preparation of SiCP / Al composite material, not only the characteristics of particle components in powder metallurgy can be adjusted freely, but also the high energy density Of the electron beam liquid phase sintering process can make the particles and the matrix of the wettability has been greatly improved; In addition, electron beam rapid manufacturing technology without mold, can effectively avoid the liquid preparation of composite materials such as the difficulty of casting, forming parts processing Therefore, the rapid electron beam manufacturing technology is a new technology suitable for the preparation of SiCP / Al composites.
