Optimal Process Parameters in ECMAP of Al−3% Mg Alloy Strips [PDF]

International Journal of Advanced Design and Manufacturing Technology, 2020
Equal channel angular pressing (ECAP) is one of the most appealing severe plastic deformation (SPD) methods. The proposed equal channel multi angular pressing (ECMAP) process enhances the efficiency of traditional ECAP technique with decreasing the ...

Review: Processing of metals by equal-channel angular pressing

, 2001
Equal-channel angular pressing (ECAP) is a processing method in which a metal is subjected to an intense plastic straining through simple shear without any corresponding change in the cross-sectional dimensions of the sample.

Geometrically Necessary Dislocations (GNDs) in iron processed by Equal Channel Angular Pressing (ECAP)

Materials Letters, 2019
The calculation of Geometrically Necessary Dislocations (GNDs) in iron processed by ECAP has been carried out via Electron Back Scatter-Diffraction (EBSD) and Transmission Electron Microscopy (TEM). Transmission microscopy reveled higher and more accurate dislocation densities than Electron Back Scatter-Diffraction at different deformation levels.
