The commercial purity zirconium (Zr702) has been deformed by Equal Channel Angular Press (ECAP) up to eight passes using route A and BC. The deformation microstructure and the bulk texture have been characterized by Electron Backscattered Diffraction (EBSD) in SEM and X-rays diffraction (XRD), respectively.

Abstract Aluminium metal matrix composites were processed by stir casting technique with commercially pure aluminium as the matrix material and 5, 10 vol.% of SiC (30 μm) particulates as the reinforcement. Al–SiC p composites were subjected to severe plastic deformation through equal channel angular pressing (ECAP).

Die for Equal Channel Angular Pressing (ECAP) process: Design and Manufacturing
2019This paper describes equal channel angular pressing process in terms of die design and die manufacturing. Equal Channel Angular Pressing process also known as ECAP is one of the most efficient process to produce high strength, hardness and toughness materials without changing its dimension by refinement of grains.

ECAP has proved to be an effective method to obtain ultrafine grain structure. Methods like extrusion are used in industries to obtain Al-based alloys, and composites as high loads for pressing are recommended for powder consolidation without very high temperatures.

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.

Finite element analysis of 6061 aluminum alloy by equal channel angular pressing (ECAP)
2012Effects 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 ...
