Effect of Equal-Channel Angular Pressing (ECAP) on Creep in Aluminium Alloys
Materials Science Forum, 2007This paper examines the effect of equal-channel angular pressing (ECAP) on creep behaviour of pure aluminium, binary Al-0.2wt.%Sc alloy and ternary Al-3wt.%Mg-0.2wt.%Sc alloy. The ECAP was conducted at room temperature with a die that had a 90° angle between the channels and 8 repetitive ECAP passes followed route BC.

Scaling up of Equal Channel Angular Pressing (ECAP) for the Production of Forging Stock
Materials Science Forum, 2006Over the past two decades equal channel angular processing (ECAP) and other severe plastic deformation (SPD) processes have been shown, in the laboratory scale, to produce material with promising properties for industrial applications. In particular, ultrafine grain (UFG) metals produced by ECAP process, for example, have been shown to exhibit higher ...

Optimization of the Equal Channel Angular Pressing (ECAP) Process for Strain Homogeneity
Materials Science Forum, 2007Two-Dimensional finite element analysis was carried out to optimize the equal channel angular pressing process (ECAP) for strain homogeneity under frictionless and frictional conditions. The effect of outside corner angle (Ψ), inner radius (r) and shear friction (m) on the strain homogeneity was investigated.

Processing of Copper by Equal Channel Angular Pressing (ECAP) – Microstructure Investigations
Key Engineering Materials, 2015The present study attempts to apply Equal-Channel Angular Pressing (ECAP) to 99.99% pure copper. ECAP process was realized at room temperature for 4, 8 and 16 passes through route BC using a die having angle of 90°. The microstructure of the samples was investigated by means both light and transmission electron microscopy.

Simulation of the Effective of Friction on the Deformation in Equal Channel Angular Pressing (ECAP)
Key Engineering Materials, 2015A influence of friction on the deformation behavior and strain homogeneity during ECAP has been studied by conducting 2D and 3D finite element simulations for a range of friction conditions m = 0 – 0.2. The deformation was more uniform in central steady zone as compared to the ends of the sample.

Abstract Equal channel angular pressing (ECAP) in the solid solution state with post-ECAP low-temperature aging treatment was found to be quite effective in enhancing the mechanical properties of 2024 Al alloy. Yield stress (YS) as high as 630 MPa could be achieved. Moreover, the ductility of ECAPed alloy was improved after the aging treatment.
