Producing High‐Strength Metals by I‐ECAP [PDF]
Advanced Engineering Materials, 2015 Incremental equal channel angular pressing (I‐ECAP) is used in this work to produce ultrafine‐grained (UFG) pure iron, aluminum alloy 5083, commercial purity titanium (grade 4), and magnesium alloy AZ31B. Pure iron is processed at room temperature, aluminum alloy at 200 °C, titanium at 320 °C, and magnesium alloy at 150 °C.

On the Effect of Natural Aging Prior to Low Temperature ECAP of a High-Strength Aluminum Alloy
Metals, 2018 Severe plastic deformation (SPD) can be used to generate ultra-fine grained microstructures and thus to increase the strength of many materials. Unfortunately, high strength aluminum alloys are generally hard to deform, which puts severe limits on the ...

Tailored Sheared Blanks Produced by Incremental ECAP [PDF]
Key Engineering Materials, 2015 Incremental equal channel angular pressing (I-ECAP) is a process used for production of continuous ultrafine grained bars, plates and sheets. Normally the thickness of the processed billet is kept unchanged in consecutive passes to enable repetitive insertion into the same die. This is achieved by controlling the bottom dead centre of the reciprocating
