| Abstract Scope |
Heterostructured materials have emerged as a promising new technology capable of enhancing strength without sacrificing ductility. Although heterostructured titanium alloys have been explored in the literature, the interplay of complex stress states, deformation mechanisms, and phase transformations has made it challenging to isolate the role of deformation pathways in heterostructure evolution. Thus, to deconvolute mechanisms, this work examines grade 2 titanium, removing microstructural contributions from phase transformations. We aim to develop a fundamental understanding of heterostructure development by simplifying the deformation environment. We utilize commercially pure titanium and a modified high-pressure torsion technique designed to introduce a controlled pressure gradient while maintaining a quasi-infinite shear regime. This processing approach allows us to systematically investigate the microstructural evolution under well-defined mechanical conditions, providing new insights into the underly mechanisms of heterostructure evolution in titanium. |
