Titanium and its alloys have been used in a broad range of products such as biomedical implants due to their high specific strength, corrosion resistance and biocompatibility. Improvement in microstructure and mechanical properties of CP titanium is usually performed by cold rolling and controlled atmosphere heat treatment that is energy-intensive and costly. This study aims to investigate the effect of an in-situ electro-plastic treatment (ISEPT) on the microstructure evolution of commercially pure (CP) titanium. The deformation load and electric current in this treatment were applied in the same direction (in-situ) to maximise the electro-plastic effect. Simultaneous electric current and strain application created a condition for dynamic recrystallization to occur at low temperature and under atmospheric conditions, thus reducing the cost and energy for manufacturing. The rapid heating and cooling prevented the oxidation of titanium to a large degree, eliminating the costly inert gas or vacuum requirement. Results in relation to the effect of applied current, strain rate, cold working and geometry on the processed CP Ti were discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
