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，在制備大尺寸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理想的組織和性能。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。The particles distributed hi the matrix of grey cast iron, but some contact each other. the composite layer extend gradually into the substrate. when volume fraction of wc is 36 wt % and 27 wt %, the matrix of the composite is high chromium cast iron, consist of white carbide bars and the austenite. wc particles distributed uniformly, retaining approximately quondam granular form in the composite layer which has an evident interface area with the substrate, with good bonding strength
對不同碳化鎢體積分數的灰鐵和低鉻鑄鐵基復合材料的微觀組織結構分析表明：碳化鎢體積分數為52時，復合層內基體為灰口鑄鐵組織，顆粒直接分佈在灰鐵基體上，部分碳化鎢顆粒有相互接觸的現象，基材與復合層之間沒有明顯的過渡；碳化鎢體積分數為36 、 27時，復合層內基體為高鉻鑄鐵，由面塊狀的奧氏體和白條狀碳化物組成，碳化鎢顆粒表面固溶於基體組織中，粒形基本保持完整，分佈均勻，與基體構成冶金結合，基材與復合層之間存在一個明顯的平緩過渡區。Being resipansible for technology guality of this unit, i have arganized and completed or then 10 great consultative projects in meteluvgical industing including feasible research repart and preliminary design of dan yang ring - type sintering plant loaned from world bank. designed no. 6 semi - contiuars rolling mill line of shagang group ; nangang group steel making plant water treatinent system, feasible research report and preliminarg design of nangang group no. 3 continuous casting machiue and hebei wwan iron making co. 24m2 rinn - tgpe sintering plant, as chief - disigner, none argamizing working drawing disign far it
