Abstract
Ti-6Al-4 V finds wide applications in industrial areas due to its unique properties. Though, how its special microstructure (i.e., properties mismatch between different phases) could influence the surface/chip formation mechanism when machining (e.g., size effect) remains unclear. In this study, cutting experiments, simulation and post-processing materials characterizations of bimodal Ti-6Al-4 V were performed. Two interesting new phenomena were revealed: (i) variation of chip segmentation mechanism from regular serrated chip to serration at phase boundary when undeformed chip thickness reduces, (ii) ‘inverse size effect’ of specific shear energy. These findings open a new window of optimizing machining parameters for this specific material.
