Shearing Patterns of AZ31 Mg Alloy Processed by Equal-Channel Angular Pressing via Various Route
, 2011 Equal-channel angular pressing (ECAP) is used to convert coarse grain into ultrafine grain (UFG). The characteristics of ECAP and the shearing patterns obtained when ECAP applied to metals are investigated.

, 2004 This thesis deals with the concept of ECAP applied to a commercial Al Mg-Si alloy (AA6082.50). A detailed analysis of the strains introduced by ECAP in a single passage through the die has been made, based on direct measurements on partially pressed samples. Further, the mechanical properties of ECAP’ed samples have been investigated.
