Secondly, the effect of transverse deforming on the property of the wedge pressing was studied. the results showed that : the wedge pressing stock with the transverse deforming amount of 10 % acquired the best performance. the highest density got the biggest rate of slope while with the amount of 30 % the curve was more some special structure and performance as following : the large porosities was crushed into small or linear ones with the high - direction deformation amount of 20 % ; as the increasing of the high - direction deforming, the particles got a further deforming, the porosities got a further crushing, the small porosities were mergered by the large ones and the former then disappeared ; when the amound reached 60 %, the quantity of the porosities would obviously decrease which made the materials compact, the microstructure more uniform and the density and hardness curves more horizontal, the relative desity could reach 99. 7 %, the tensile strength b of the as - compacted samples reached 408mpa with the yield strength s teached 289mpa and the elongation percentage reached 13. 6 %. in addition, the microstructure of the wedge pressing stock under the pressing temperectureof 450 was uniform, the porosities and the boundries of the grains basically disappeared and the conjunction between particles was great
採用雙向楔形
壓制，大尺寸噴射沉積5a06
鋁合金楔
壓坯的組織和性能變化具有如下特點:當高向變形量為20 %時，大的孔洞變形破碎為小的孔洞，或呈線狀孔;隨著高向變形量的增加，顆粒進一步變形，孔洞進一步破碎，大孔「吞併」小孔，小孔塌陷並逐步消失;當高向變形量達到60 %時，孔洞量大為減少，材料基本緻密，組織趨于均勻，楔
壓坯料的密度、硬度變化曲線接近水平線，坯料的相對密度達99 . 7 % ，抗拉強度_ b = 408mpa ，屈服強度_ （ 0 . 2 ） = 289mpa ，
延伸率= 13 . 6 % ;對比其它的
壓制溫度，在450楔形
壓制的坯料組織均勻，孔洞及顆粒邊界基本消失，顆粒之間冶金結合良好。
