Precipitation hardening in dilute Al–Zr alloys
Autor: Pedro Henrique Lamarão Souza, Carlos Augusto Silva de Oliveira, José Maria do Vale Quaresma
Publikováno v: Journal of Materials Research and Technology, Vol 7, Iss 1, Pp 66-72 (2018)
The aim of this study was to investigate the effect of solute content (hipoperitectic Al–0.22 wt.%Zr and hiperperitectic Al–0.32 wt.%Zr) on the precipitation hardening and microstructural evolution of dilute Al–Zr alloys isothermally aged. The

Publikováno v: Materials Research, Vol 20, Iss 6, Pp 1600-1613 (2017)
The microstructure and microhardness of isothermally aged Al-0.22Zr and Al-0.32Zr alloys were investigated. Peak microhardness occurred after aging at 650K for 100 h for both alloys and decreased slightly after aging at 400 h. Nanometer-scale spheric

Simultaneous Improvement of the Electric Conductive and Mechanical Properties of Nanostructured Aluminum Alloy
Autor: José Maria do Vale Quaresma, Vinicius Silva dos Reis, Cristian Loayza, Marcos Al dos Reis, Emerson Rodrigues Prazeres, Victor Melo, Eduardo de Magalhães Braga, José Galdêncio da Silva
Aluminum nanocomposites demonstrate improvements in the mechanical properties, as well as in thermal and electric conductivity. The incorporation of multiwalled carbon nanotubes (MWCNT) in the aluminum matrix, using conventional melting methods, is a
