Journal ArticleDOI
Studies of light alloys by positron annihilation techniques
TL;DR: In this article, the potential of positron annihilation spectroscopy (PAS) in the study of light alloys is illustrated with special regards to age-hardening, severe plastic deformation, fatigue and fracture in aluminium- and magnesium-based alloys.
Journal ArticleDOI
Stability of vacancies during solute clustering in Al-Cu-based alloys
TL;DR: In this article, a direct comparison between Al-Cu and Al-Mg alloys showed that the mechanism by which Mg affects the microstructure and the aging kinetics of the alloys is related to the formation of vacancy-cu-mg complexes that act as embryos for the nucleation of coherent solute clusters.
Journal ArticleDOI
Microstructural evolution of 7012 alloy during the early stages of artificial ageing
TL;DR: In this paper, a study of the microstructural evolution of a commercial 7012 age-hardenable alloy following artificial ageing by high resolution and conventional transmission electron microscopy and positron annihilation lifetime spectroscopy is presented.
Journal ArticleDOI
Positron-annihilation study of the aging kinetics of AlCu-based alloys. I. Al-Cu-Mg
TL;DR: In this article, the aging kinetics and the association of vacancies to solute elements during precipitation in an Al-Cu-Mg alloy with high Cu/Mg ratio were investigated.
Journal ArticleDOI

TL;DR: In this paper, the authors investigated the dependence of the physical properties of styrene-butadiene rubber copolymers (cured with different sulphur content, in order to obtain various networks) on the crosslink density by means of dynamical mechanical analysis, differential scanning calorimetry and positron annihilation lifetime spectroscopy.
