Precipitation induced room temperature superplasticity in Zn-Cu alloys

Room temperature precipitation in quenched Al - Cu - Mg alloys : a model for the reaction kinetics and yield strength development

The microstructural evolution during low temperature ageing of two commercial purity alloys (Al1.2Cu-1.2Mg-0.2Mn and Al-1.9Cu-1.6Mg-0.2Mn at.%) was investigated. The initial stage of hardening in these alloys is very rapid, with the alloys nearly doubling in hardness during 20 h ageing at room temperature. The microstructural evolution during this stage of hardening was investigated using diffe...

ANELASTIC EFFECTS IN SINGLE CRYSTALS OF -Cu-Zn AND -Cu-Zn-Al ALLOYS

Electrodeposition of Zn, Cu, and Zn-Cu Alloys from Deep Eutectic Solvents

Deep eutectic solvents (DESs) comprising choline chloride (ChCl) with either urea or ethylene glycol (EG) have been successfully used as powerful and potential electrolytes for extracting metals from their corresponding metal oxide precursors. In this work, for electrodeposition of Zn and Zn-Cu alloys, ChCl/urea-based DES was employed. Cyclic voltammetry study demonstrates that the reduction of...

Electrodissolution of Cu-Zn Alloys in Acetate Media

A eletrodissolução de ligas de Cu-Zn, de diferentes composição química (CuZn37 e CuZn39Pb3) foi estudada em solução tampão de acetato, pH 5, através de medidas de potencial de circuito aberto e voltametria cíclica, sob condições estáticas e dinâmicas. A menor resistência à corrosão detectada nestas ligas, comparativamente ao Cu puro, foi atribuída à estrutura da camada anódica formada ZnO.x H 2...
