Abstract: Combining of rotary extrusion and equal channel angular pressing (ECAP) leads to the ECAP-Conform process, which is one of the few successful continuous severe plastic deformation processes. Sample before reaching the ECAP die is influenced by three main deformations of rolling, bending, and forging, which can affect the microstructure and mechanical properties of the material. The effects of these steps on the microstructure and properties of AA1100 alloy are studied based on the simulation and experimental investigations. It is found that these steps significantly affect the material and they should be considered for evaluation of properties compared with the conventional ECAP.
Keywords: severe plastic deformation, Microstructure, Aluminum, extrusion, Ecap Conform Process, equal channel angular pressing

very useful article
It is a very useful article which is talks about the manner of Al1100 in Conform channel. by this article you can find why the Conform is better and more useful than conventional ECAP process.
