Processamento do cobre por EACI
(Universidade Federal de Minas GeraisUFMG, 2008-01-28)
Billets of copper were processed under four passes of equal channel angular pressing.The mechanical properties of material were evaluated through compression e microhardness tests. The microstructures of samples of cross ...
Estabilidade microestrutural da liga Cu-0,8Cr-0,07Zr após extrusão em canal angular em temperatura criogênica
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2021-12-20)
Severe Plastic Deformation (SPD) are well established routes with regard to the
intense microstructural refining of metals and alloys up to the submicrometer (<
1 μm) and/or nanometer (< 100 nm) scales. Lowering the ...
Comportamento mecânico da liga Al 6351 submetida à extrusão angular em canais iguais e compressão multiaxial cíclica
(Universidade Federal de Minas GeraisUFMG, 2017-02-07)
Equal Channel Angular Pressing (ECAP) is a severe plastic deformation process of metals that can supply samples with large dimensions at high production rates. Multi Axial Compression (MAC) is also a severe plastic deformation ...

The growing need for materials with multifunctional properties has motivated the
development of new alloys and processing techniques. Among these materials, the high
strength ones obtained via SPD (Severe Plastic ...
The texture development of ECAP processed AA1050aluminum, before and after a final anneal: effect of the initial texture
(IOP Publishing, 2014-10)
Equal Channel Angular Pressing (ECAP) can be used to control deformation and annealing textures. The initial texture has a significant role on texture development and intensity after deformation and anneal. In this work ...
