Title
Application of tool vibration in die pressing of Ti-powder
Abstract
Titanium and its alloys have a vast range of applications in the chemical, aeronautical and aerospace industries as well as in medical engineering, based on their high specific strength and high corrosion resistance. Regarding the fact that titanium is an expensive material, powder metallurgy can be a notably economized production solution which offers the maximum material utilization compared to shape cutting processes. Among all forming processes of metallic powder, die pressing is one of the most widespread processing methods. A common effect of this method is residual porosity in the produced parts, which has negative impacts on their mechanical stability. This study shows how the porosity can be reduced by means of induced vibration in the pressing tool. Consequently, the mechanical properties of the product can be improved. Further studies are aimed at investigating the methods of increasing the homogeneity of density allocation.
