Study by DSC and HRTEM of the aging strengthening of Cu-Ni-Zn-Al alloys
(Elsevier, 2016)
The structural changes of a Cu-12 wt.% Ni-17 wt.% Zn-1.7 wt% Al alloy as a function of the aging temperature have been studied by means of Differential Scanning Calorimetry (DSC), high resolution transmission electron ...
Two-Phase Dendrite and Bimodal Structure in an Al-Cu-Ni Alloy: Their Roles in Hardness
(2022-01-01)
With the increasing interest in developing Al-Cu-Ni alloys for use as structural material comes the need to understand more about their processing–microstructure–properties relationships. In this work, an unsteady-state ...
Atomic ordering in Cu-Al-Ni: Point approximation and Monte Carlo simulations
(Elsevier Science, 2017-02)
Long range ordering in the bcc phase of the Cu-Al-Ni alloy is modelled through the analytical Bragg-Williams approximation and by means of numerical Monte Carlo simulations. The interchange energies that govern the ordering ...
Microstructure features and mechanical/electrochemical behavior of directionally solidified Al−6wt.%Cu−5wt.%Ni alloy
(2021-06-01)
The effects of the addition of 5.0 wt.% Ni to an Al−6wt.%Cu alloy on the solidification cooling rate T˙ growth rate (VL), length scale of the representative phase of the microstructure, morphology/distribution of intermetallic ...
Unión brazing y evaluación de la resistencia al corte del par disímil compósito TiC/Cu-20Ni a su metal matriz
(Universidad Michoacana de San Nicolás de Hidalgo, 2022-02)
TiC-reinforced metal matrix composites have significant applications in the aerospace and automotive sectors due to the structural and functional properties that they are capable of offering. To improve their functionality, ...
Ion implantation inducing two-way shape memory effect in Cu-Al-Ni thin films
(Elsevier Science, 2019-11)
We report two-way shape memory effect (TWSME) induced by Al ion implantation in 6 μm thick Cu-Al-Ni thin films. The films display an average grain size of 3.7 μm and a martensitic transformation temperature (MS) of ≈ 240 ...
Highly Selective Cu-Modified Ni/SiO2–Al2O3 Catalysts for the Conversion of Maleic Anhydride to γ-Butyrolactone in Gas Phase
(Springer/plenum Publishers, 2015-07-30)
The gas phase hydrogenation of maleic anhydride (MA) to succinic anhydride (SA) and the subsequent hydrogenolysis to γ-butyrolactone (GBL) was studied on SiO2-Al2O3-supported Ni catalysts modified with Cu and prepared by ...
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, ...
