Production of nano-sized grains in powder metallurgy processed pure aluminum by equal channel angular densification (ECAD) and equal channel angular pressing (ECAP)

Materials Testing, 2015
Abstract In this study, pure aluminum powders were turned into bulk material using equal channel angular densification (ECAD)/equal channel angular pressing (ECAP) and further deformed up to 16 passes at 100 °C. For comparison, pure aluminum powders were also compacted in a mold without ECAD/ECAP process at the same temperature.

Effect of Secondary Mg17Al12 Phase on AZ80 Alloy processed by Equal Channel Angular Pressing (ECAP)

Silicon, 2015
AZ80 alloy was subjected through Equal Channel Angular Pressing (ECAP) to refine the grains at three different temperatures 548 K, 573 K, and 623 K up to 4 passes for route Bc, where the specimen is rotated 90∘ counter-clockwise direction for each pass.

Analytical and Numerical Modelling of Strain and Strain Rate in Equal Channel Angular Pressing (ECAP)

Key Engineering Materials, 2006
Equal channel angular pressing (ECAP) is a convenient forming procedure among various severe plastic deformation processes. It is based on extruding material through specially designed entry and exit channel dies to produce an ultrafine grained microstructure.

Finite element analysis of 6061 aluminum alloy by equal channel angular pressing (ECAP)

2012
Effects of central angle, frictional coefficient on the forming of ECAP were analyzed by simulating ECAP process of 6061 aluminum alloy at room temperature with the help of FEM (finite element method). The results reveal that with decreasing in central angle, equivalent strain of the samples is increased with more homogeneous distribution, however ...
