1. Texture analysis in ultrafine grained coppers processed by equal channel angular pressing
Electrolytic tough pitch (ETP) and fire refined high conductivity (FRHC) copper samples were severely deformed at room temperature by equal channel angular pressing (ECAP) up to 16 passes (ε ~ 1 per pass), following route Bc. The effect of the initial texture on the evolution of texture after the ECAP process for both materials was analyzed. The annealed ma

2. Influência da temperatura e corrente de trabalho, nas características elétricas e mecânicas do cobre eletrolítico
Fatores críticos no controle de um sistema elétrico, sem dúvida alguma, são os desafios de manter-se toda a sua estrutura física em plenas condições de operação. A infra-estrutura passiva, materiais e acessórios, devem manter suas propriedades elétricas e mecânicas, minimizados aos impactos da descaracterização por excedentes de correntes elét

3. The influence of die geometry on stress distribution by experimental and FEM simulation on electrolytic copper wiredrawing
The study of die geometry is vital in determining the surface and mechanical properties of drawn wires, and consequently, their application. In this work, annealed electrolytic copper wire (ETP), with 0.5 mm original diameter was reduced by 19% in dies with 2β = 10º and 18º and Hc = 35 and 50%. The best experimental results were then studied by the Finite
