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。 -
The main research outputs of this paper are as follows : l. baed on the choosing rational mix proportion, the influence of changing volume proportion of steel fiber on mechanical properties such as crushing resistance, splitting resistance, breaking resistance and bending resistance and the variation rule of mechanical properties are studied by experiment and theoretical analysis of 320 samples. according to experimental results of different layered structure of fiber - reinforced concrete, the influence of layered height on splitting strength and breaking strength is discussed. so it offers reliable reference to design road structure by using fiber - reinforced concrete
在選擇了合理的配合比基礎上，通過對320塊試件的試驗和理論分析，研究了鋼纖維體積率的變化對抗壓、劈拉、抗折以及彎曲韌性等力學性能的影響及變化規律，由不同分層試件的試驗結果，探討了鋼纖維混凝土的分層高度對劈拉、抗折等強度影響，為鋼纖維混凝土的路面結構設計提供了可靠的依據。 -
