Accumulative Roll Bonding (ARB), a severe plastic deformation technique, was used in this study to process
commercially pure titanium (CP-Ti) sheets at selected warm temperatures. Post-processing treatments at selected
conditions were also performed on the ARB processed material, following each ARB processing cycle. Mechanical
characterization and microstructural examination were carried out on the processed and post processed material
to track the evolution of the microstructure, the changes in strength and ductility, and their relationships with
regard to one another. Though the temperatures and processing conditions covered here are limited, it was found
that ARB processing temperature affects the resultant flow behavior of the material. Furthermore, it was shown that
post processing treatment of the ARB processed material can increase both strength and ductility of the material;
the latter can be used as an effective tool for further controlling the structure and properties of the ARB-processed
material.
