  1. 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

    坩堝移動式噴射沉積技術作為一種先進的材料制備新技術,在制備大合金及金屬基復合材料方面具有顯著的優越性。然而噴射沉積坯件特別是大型坯件通常存在一定量的孔隙,顆粒表面存在一定量的氧化膜,顆粒之間未能完全達到良好的冶金結合狀態,因此需要進行后續緻密化和塑性變形才能獲得的組織和性能。本文採用一種新型的楔形壓制工藝,即通過局部變形、多道次小變形累積實現大變形的緻密化加工方法,對噴射沉積多孔坯料進行后續緻密化和塑性變形,很好地解決了傳統加工工藝的難題,大大降低了生產成本。
