Abstract：

By the finite element analysis software,the influence of one-sided wedge pressing was studied under different pressing speeds and different cyclic pressing temperatures on the deformation and densification of spraying deposited 5A06 aluminum alloy.The result shows that the average relative density ρ rises with pressing down speed's rising,densifying fairly good.With the deformation temperature rising,damage value increases first,and then decreases.Damage value is bigger at 400 ℃.After analying in general,it is found that the reasonable velocity of cyclic pressing is 0.5-1.0 mm·s-1 and the reasonable temperature of cyclic pressing is 450-500 ℃.
