The Influence of Archaeometallurgical Copper Alloy Castings Microstructure towards Corrosion Evolution in Various Corrosive Media

open access: yesCorrosion and Materials Degradation, 2021
The local patterns at the interfaces of corrosion stratification, developed on two archaeometallurgical bronzes (a Cu-Sn-Pb and a Cu-Zn-Sn-Pb alloy), in the as-cast condition, were assessed by OM and SEM-EDS systematic elemental chemical analyses ...

Effect of Thickness Reduction on Cold Rolling Process to Microstructure and Brass Hardness

open access: yesMATEC Web of Conferences, 2018
Brass is an alloy between copper (Cu) and zinc (Zn) where the majority of the elements are copper. Brass that undergoes a cold rolling process will experience changes in microstructure and mechanical properties.

Effect of cold rolling and annealing temperature to the characteristics of α + β' phases in Cu-29.5Zn-2.5Al alloy produced by gravity casting [PDF]

open access: yesJournal of Mining and Metallurgy. Section B: Metallurgy, 2020
Al-brass alloys (Cu29.5Zn2.5Al wt. %) were produced by gravity casting and homogenized at 800°C for 2 h, resulting in a binary phase morphology identified as cubic α and martensitic βʹ phases through X-ray diffraction (XRD).

Electropolishing Behaviour of 73 Brass in a 70 vol % H3PO4 Solution by Using a Rotating Cylinder Electrode (RCE)

open access: yesMetals, 2017
The electropolishing behaviour of 73 brass was studied by means of a rotating cylinder electrode (RCE) in a 70 vol % H3PO4 solution at 27 °C. Owing to the formation of a blue Cu2+-rich layer on the brass-RCE, an obvious transition peak was detected from ...

On the correlation of shear band formation and texture evolution in $\alpha$-brass during accumulative roll bonding

open access: yes, 2018
We studied the microstructural evolution of the low stacking fault energy $\alpha$-brass alloy CuZn15 during accumulative roll bonding (ARB). Most notably, the typical brass-type texture was clearly observed after four ARB passes (approx.
