Formation of ultrafine-grained (UFG) structure and mechanical properties by severe plastic deformation (SPD) [PDF]
Commercial pure cooper (99,9% Cu) was deformed by equal channel angular pressing (ECAP) using up to 10 passes, route C. The evolution of microstructure and fracture character were observed by OM, SEM and TEM. The mean grain size decreased with increasing

Grain Growth during Annealing of Ultrafine-Grained and Nanomaterials
Ultrafine-grained metals and alloys with a submicrocrystalline structure in some cases demonstrate a set of unique properties, for example, high strength and hardness, low-temperature superplasticity at high strain rates, and improved electrical and ...

Severe plastic deformation by Equal Channel process
Neprestanim napretkom i razvojem znanosti te zbog sve rigoroznijih zahtjeva tehnologije, javlja se izrazita potreba za novim materijalima, boljih mehaničkih svojstava, a istovremeno male mase.

A model of grain refinement and strengthening of Al alloys due to cold severe plastic deformation
This paper presents a model which quantitatively predicts grain refinement and strength/hardness of Al alloys after very high levels of cold deformation through processes including cold rolling, equal channel angular pressing (ECAP), multiple forging (MF)

Severe Plastic Deformed Pure Aluminum by Equal Channel Angular Pressing
Samples of an aluminum alloy were subjected to an equal channel angular pressing (ECAP) at room temperature for one pass. For the several specimens severe plastic deformation process was interrupted to observe the material flow.
