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.

Superplastic properties of Pb–62%Sn eutectic alloy after equal channel angular pressing (ECAP)
Journal of Materials Processing Technology, 2008Abstract Billets of Pb–62%Sn alloy were subjected to equal channel angular pressing up to various numbers of pressings of 1, 4, 8 and 16 passes via route BC at room temperature in order to investigate its superplastic properties. These samples were pulled to failure in an Instron machine at a temperature of 413 K at initial strain rates ranging from ...

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 ...
