Abstract. Equal channel angular pressing (ECAP) as a severe plastic deformation (SPD) technique was employed for consolidation of AZ31 magnesium chips. The chips were consolidated at temperature 300 °C following ECAP route A up to two passes. optical and scanning electron micrographs reveal that have taken place the quality improves with number passes hence total imposed strain. Vickers hardnes...

In this article, commercially pure copper samples were severely deformed by equal channel angular pressing (ECAP) up to eight passes at room temperature. The effects of severe plastic deformation on the microstructure, mechanical properties, and electrical conductivity of the copper were investigated. The microstructure evolution was followed by optical microscope and field emission scanning el...

This paper was aimed at verification of functionality of the ECAP technology at extrusion of the copper, alluminium alloys and steel. Experiments were made on equipment, which is demonstrated in the Fig 1. Deformation forces were measured during extrusion, resistance to deformation was calculated and deformation speed was determined approximately. Analysis of structure was made with use of ligh...

The mechanical properties and deformation behavior of a Cu-Cr-Zr alloy after solution treatment (ST) or aging (ST+AT) equal channel angular pressing (ECAP) at elevated temperature were investigated. ECAP led to strengthening degradation plasticity compared with the initial state. 1 2 passes 200 °C was almost same. An increase in promoted uniform strain plasticity. number gradual strength. YS UT...

The purpose of this study was to evaluate the corrosion behavior 1010 steel processed by Equal Channel Angular Pressing (ECAP), a technique that induces severe plastic deformation (SPD) in materials. samples were one and two passes ECAP throught routes A C. using potentiodynamic polarization electrochemical impedance spectroscopy, NaCl (pH= 6.5) sodium hydroxide/sodium phosphate 10.5) solutions...
