| Abstract Scope |
The difficulty of forming titanium alloys at room temperature is well researched and is mostly attributed to their ability to form a strong crystallographic texture during plastic deformation. Also, one major issue of concern linked to the forming of such alloys is their high sensitivity to surface inhomogeneity. Various machining processes are utilised in preparing sheet hole edges for edge flanging applications. However, the response of edge forming tendencies of titanium to different edge surface finishes is not well investigated. The hole expansion test was used in this project to elucidate the impact of selected cutting techniques and edge finish integrities on the edge formability of CP-Ti (Grade 2) and Ti-3Al-2.5V alloys at room temperature. The results show that, the quality of the cut edge surface finish has major effect on the edge formability of the material. The paper explores the reasons and consequences for this for industrial forming operations. |
