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 ...
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 ...
Influência da adição de Co e Ni e da taxa de resfriamento na microestrutura de solidificação, nas propriedades mecânicas e na corrosão de ligas Al-Si-Cu-Zn-Fe
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2022-11-28)
An important strategy by 2050 will be to transform the production of recycled Al-Si alloys as a viable and sustainable source to reach the global demand for Al. The challenge will be to mitigate the deleterious effects ...
Transformações de fase termoelásticas em ligas com memória de forma a base de Cu-Al-Ni
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2016-02-26)
Shape memory alloys (SMA) have some exceptional properties such as the
shape memory effect and the superelasticity. Both are associated with a
martensitic/austenitic phase transformation. Alloys of the system Cu-Al-Ni, ...
Numerical simulations of the pseudoelastic effect in CuZnAl shape-memory single crystals considering two successive martensitic transitions
(IOP Publishing, 2016-01)
Shape memory alloys (SMAs) with double martensitic transitions are potential candidates for highly effective, nonstandard mechanical damping systems. This paper presents a numerical model that can be used to simulate ...
