Formation of ultrafine-grained (UFG) structure and mechanical properties by severe plastic deformation (SPD) [PDF]

open access: yesMetalurgija, 2008
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

Stvaranje ultrafino zrnate (UFZ) strukture i mehanička svojstva sa intenzivnom plastičnom deformacijom (IPD)

open access: yesMetalurgija, 2008
Trgovački čisti bakar (99,9%) deformiran je kanalnim kutnim prešanjem (KKP) do 10 provlaka-putanje. C. Razvitak mikrostrukture i karakter loma praćeno je sa OM, SEM i TEM. Veličina zrna se smanjuje povećanjem deformacije poslije 10 provlaka na 100-300 nm.

Grain Growth during Annealing of Ultrafine-Grained and Nanomaterials

open access: yesУспехи физики металлов
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 ...

The Impact of Particle Reinforcement with Al2O3, TiB2, and TiC and Severe Plastic Deformation Treatment on the Combination of Strength and Electrical Conductivity of Pure Aluminum

open access: yesMetals, 2019
It has been found that a high electrical conductivity of 63.1%, the International Annealed Copper Standard (IACS), and high mechanical properties are achieved by the initial aluminum alloy after undergoing four cycles of the severe plastic deformation ...

A model of grain refinement and strengthening of Al alloys due to cold severe plastic deformation

open access: yes, 2012
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

open access: yesThe Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials Science, 2009
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.
