Naizabekov, Mining and Metallurgy Faculty, Rudny Industrial Institute, Rudny, Kazakhstan In the present research, equal channel angular pressing (ECAP) was conducted. The defectness degree of the alloy for one pass and maximum strain was determined. Ultra fine grained...

in the present study, mechanical properties and low cycle fatigue behavior of a solid-solutionized aa6061 aluminum alloy produced by equal channel angular pressing (ecap) process were investigated. the grain refinement after two passes of ecap significantly increased the yield stress and ultimate tensile stress and decreased the ductility of the alloy. however, the improvement of low cycle fati...

Equal channel angular pressing (ECAP), expansion equal (Exp.-ECAP), and hybrid (HECAP) or (Hybrid ECAP) processes were applied to pure copper specimens within this study. After the application of ECAP, die used in Exp.-ECAP process was optimized considering strain inhomogeneity specimen maximum load that occurred during process. Finite element method (FEM), artificial neural network (ANN), gene...
