Single Roll Drive Equal Channel Angular Process –a Potential Severe Plastic Deformation (SPD) Process for Industrial Application
Single roll drive equal channel angular process (SRD-ECAP) is derived from classical equal channel angular pressing (ECAP). It overcomes the drawbacks of ECAP, which is a discontinuous process and can only process short billets with invariable square or round section. SRD-ECAP, however, can process long billets continuously. In addition, it can also process sheet or strip. Another merit is that diameter or thickness of billets processed is adjustable. The structure of SRD-ECAP is quite simple and easy to be realized. In this paper, stress analysis has also been carried out. It is believed that SRD-ECAP can be a potential severe plastic deformation (SPD) process for Industrial Application.
