Thermal behavior of alpha-(Cu-Al-Ag) alloys
(Springer, 2007-03-01)
Thermal behavior of alpha-(Cu-Al-Ag) alloys, i.e. alloys with composition less than about 8.5 mass% Al, was studied using differential scanning calorimetry (DSC), differential thermal analysis (DTA), scanning electron ...
A simple model to predict long-range atomic ordering temperatures in Cu-based shape memory alloys
(Taylor & Francis, 2014-06)
The order–disorder and order–order phase transition temperatures in the austenitic phase of Cu-based shape memory alloys were used to obtain a set of first- and second-neighbour pair interchange energies. To this end, a ...
Spectrophotometric determination of zinc in copper-base alloys with TAN
(1995)
TAN reacts with zinc(II) forming a red complex with composition 1:2 Zn(II)-TAN and absorption maximum at 582 nm. Zinc can be determined with this reagent in the presence of Triton X-100, in the pH range 6.20-8.00 with a ...
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, ...
Production of copper-based metallic glasses: evolution of the phases during mechanical alloying.
In this study, different, copper-based materials were fabricated under equal milling conditions (SPEX 8000D, argon atmosphere, stearic acid, BPR = 10:1) and variable amounts of time, from 1 to 120 hours, in order to compare ...
Influence of silver additions on the thermal behavior of the Cu-8 mass% Al alloy
(Kluwer Academic Publ, 2001-01-01)
The influence of additions of 2, 4, 6, 8, 10 and 12 mass% Ag on the thermal behavior of the Cu-8 mass% Al alloy was studied using differential scanning calorimetry (DSC), scanning electron microscopy (SEM), energy dispersive ...
