چکیده مقاله:

Presently demands for materials showing simultaneously appropriate strength and ductility is a drastic challenge. It is worth mentioning CP-Ti is an applicable material particularly for Aerospace and Bio fields. As-received CP-Ti represents relatively poor quality in terms of strength that could be solved successfully through performing Equal Channel Angular Pressing (ECAP). The most important disadvantage is that the ECAP contributes to a slump in the ductility, hence the subsequent forming processes encounter serious limitation in form of formability. In order to escalate ductility and formability of the mentioned material, Warm Caliber Rolling (WCR) has been used after ECAP. As obtained based on results of this study, specimens which underwent WCR showed the uniform plastic deformation during passes. Also higher workability of them is another advantage of post-WCR process.
