Designing tools for ECAP processing — •Mikhail V. Popov, Torbjørn Lamark, Ralph Jörg Hellmig, and Juri Estrin — Institut für Werkstoffkunde und Werkstofftechnik, TU Clausthal, Agricolastr. 6, 38678 Clausthal-Zellerfeld

In recent years Equal Channel Angular Pressing (ECAP) became one of the most important methods for the production of ultrafine grained materials. General ECAP tools are simple in design, but to have really good processing conditions to achieve homogeneous microstructures more advanced tools including features like backpressure or even sliding walls are necessary. In this talk, an introduction on the critical parameters of ECAP processing will be given followed by a discussion of possible solutions for obtaining high performance ECAP equipment.
