Effects of Zr on the amorphization of Cu-Ni-Zr alloys prepared by mechanical alloying
(Elsevier Science SA, 2018-10-15)
This work presents the effects of high energy milling with different Ni and Zr ratios on the amorphization of ternary Cu-Ni-Zr alloys (initially, Cu-43Ni-7Zr, Cu-12Ni-31Zr, Cu-33Ni-7Zr, and Cu-12Ni-23Zr; and later, ...
Relationship between grain size and thermal hysteresis of martensitic transformations in Cu-based shape memory alloys
(Pergamon-Elsevier Science Ltd, 2017-07)
The effect of grain size on thermal hysteresis is studied in ribbons and thin strips obtained by rapid solidification techniques. Results show a strong increase of the hysteresis width when the grain size is below ∼100μm. ...
Corrosion Resistance of Aluminum-Copper Alloys with Different Grain Structures
(Springer, 2020-11)
Electrochemical studies and microstructure analysis of directionally solidified hypoeutectic and eutectic aluminum-copper alloys were performed. Optical and scanning electron microscopy studies of corroded specimens with ...
New cyanide-free alkaline electrolyte for the electrodeposition of Cu-Zn alloys using glutamate as complexing agent
(Electrochemical Society, 2019-01)
Glutamate is a potential replacement of cyanide in alkaline electrolytes due to its capability to form complexes with bivalent metal ions. Since promising results were achieved with copper and zinc plating baths, and the ...
The Microstructure and the Phase Stability of a Cu–30at.%Al Alloy Obtained by Reactive Milling and Quenching
(Springer, 2020-12)
The phase stability of a Cu–30at.%Al milled and quenched is studied by differential scanning calorimetry and in situ high-temperature X-ray diffraction (HT-XRD). This analysis was performed from room temperature to 700 °C. ...
Oxygen reduction on Cu–Zn alloys
(Springer, 2008-09)
The reduction of oxygen on brass type Cu77Zn21Al2 in contact with 0.1 mol L-1 borax at pH 9.2 with and without chlorides was investigated and compared with the results on spectroscopic Cu. The surface film was characterized ...

Corrosion behavior of a β CuAlBe shape memory alloy containing stress induced martensite
(Elsevier Science, 2019-02)
The corrosion behavior of a β CuAlBe shape memory alloy containing stress-induced martensite was analyzed after 60 days of immersion in a 3.5% NaCl solution. The stress-induced martensite was retained in the sample after ...
Copper and brass aged at open circuit potential in slightly alkaline solutions
(Pergamon-Elsevier Science Ltd, 2009-12)
Surface oxide films were grown on 99.99% copper and brass (copper-zinc alloy, Cu77Zn21Al2) in 0.1 mol L-1 borax solution at open circuit potential and were characterized using various experimental techniques. The composition ...
