Abstract
The large strain extrusion-machining process has been used to refine the microstructure in a Titanium alloy (Ti-6Al-4V). The unconstrained cutting or machining of Ti-6Al-4V entails the formation of shear localized chips at nearly all cutting speeds, thereby hindering the use of extrusion-machining to produce fine-grained materials. The present effort attempts to suppress shear localization by the suitable modification of texture in Ti-6Al-4V through the cold-rolling process prior to extrusion-machining. Ti-6Al-4V plates were cold rolled to 30, 40, 45, and 47% thickness reductions. These textured plates were extrusion machined using a suitably designed fixture leading to fine-grained continuous foils with increased hardness. Microscopy has revealed that the suppression of shear localization in the foils produced from plates which are cold rolled to more than 40% of thickness reduction is triggered by texture formation. For thickness reductions slightly lower than 40% (e.g., 30%), suppression can be achieved only by a combination of texture and extrusion. Copyright © Materials Research Society 2017.
