Equal-Channel Angular Extrusion (ECAE): From a Laboratory Curiosity to an Industrial Technology

Numerical Analysis of Az61 Magnesium Alloy Extrusion Process by Modified Equal Channel Angular Extrusion (ecae) Method

T. Bajor, M. Krakowiak, P. Szota, Czestochowa University of Technology, Czestochowa, Poland The paper presents the results of numerical modelling of AZ61 magnesium alloy hot deformation using modified ECAE method. The temperature-velocity conditions were analysed using FEM. The extrusion process was realised using the die with modified angular channel containing horizontal contracting zone in t...

A new design for equal channel angular extrusion

A new die design has been proposed for processing of materials using Equal Channel Angular Extrusion (ECAE). The proposed design is an improvement over the existing ones and has an additional attribute to process materials at high temperatures (up to 500 oC). The design has been tested for different materials at different temperatures and it has shown the benefit of reducing the load requiremen...

Quasi-Static and Dynamic Characterization of Equal Channel Angular Extrusion (ECAE) –Processed and Rolled AZ31 Magnesium Alloy Sheet

investigating the effects of expansion equal channel angular extrusion (exp-ecae) on the dynamic behavior of aa7075 aluminum alloy

expansion equal channel angular extrusion (exp-ecae) is a severe plastic deformation (spd) operation for processing bulk materials. in the current study, aa7075 al was spd-processed by expansion equal channel angular extrusion (ex-ecae) at various temperatures and ram velocities. then, using split hopkinson pressure bar (shpb), the severely deformed products were compressed at room temperature ...
