Processing Methods of Fine-grain Materials (ECAP)

Method of equal-channel angular pressing (ECAP) is very significant SPD method whereby we are able to obtain a bulk material with UFG structure. This research deals with fundamental principles of ECAP method, an influence of the constructional design of a pressing channel and factors related to processing modes on properties of a final structure. Further, this research describes some modifications of a conventional ECAP method and processes based on its principle
