As an advanced materials preparation technology, spray - deposition has shown remarkable superiority in producing large - sized alloys and metal matrix composites. however, the spray deposeted preforms usually contain a certain quantity of porosity. besides, the oxide films on the surface of the particles lead to week metallurgic conjunction between the particles. in order to obtain an ideal structure and performance, the porous preforms need further densifying and plastical forming. in this paper, a new technology named wedge pressing was used to densify spray - deposeted 5a06 aluminium alloy, in which the large deformation can be obtained through the sum - up of local deformation and multi - step small deformation. this method can also solved the problems in traditional processing and greatly decreased the producing cost. what ’ s more, the reserch on the wedge pressing desification rules about the large - sized spray deposeted preforms was significant it was vital not only to the further densification of the prefoums but also to the further research on plastical deforming the research was also benefit to the industrialization an the application of the spray deposeted porous materials
