Abstract
Tubular channel angular pressing (TCAP) is a new and novel severe plastic deformation (SPD) technique suitable for fabrication of bulk nanograined tubular materials. There are several parameters in the TCAP process. The present paper investigates the effects of curvature angles, deformation ratio (maximum radius during TCAP/initial radius) and deformation direction on the plastic deformation behavior, strain homogeneity and required loads in TCAP processing. The results showed that higher curvature angles (ψ 1 and ψ 3) leads to better strain homogeneity while have not having any significant effect on the process loads. Also, at the second curvature angle of 90°, the best condition is achieved with good strain homogeneity and lower load requirements rather than lower angles. Investigation of deformation direction showed that inlet deformation direction causes tube thinning at the end of the process, and thus, using the inlet case is not recommended.
