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
