Abstract
Materials processed by severe plastic deformation (SPD) achieve ultrafine grain (UFG), thus making them suitable for advanced engineering applications. Equal channel angular pressing (ECAP) is one of the most popular techniques of SPD process which imposed ultra-large plastic strain on bulk material to produce a UFG metal. These techniques extrude the materials through a specially designed die channel without significantly changing in die geometry. In an ECAP process, with increase in the number of pass, more grain refinement is possible, but it is rarely used due to practical difficulties in implementation. In order to overcome such difficulties, the ECAP channel with more number of turns is used to enhance the grain refinement of long billet in a single pass. Two-turn ECAP die is one of them to double the amount of plastic strain in a single pass with following route C rotation while process repetition is still open for more grain refinement. This paper describes new incremental ECAP channel (three-turn) of SPD process and followed by route A rotation. In order to find the processes parameter as well as die geometry of V-shape ECAP channel, an FEA simulation of S-shape ECAP channel with validation has been carried out, and process kinematics are established.
