To study the vacancy-solute-atom interaction, diluted Al-In and Al-Sn alloys with 0.005 and
0.025 at.% indium/tin cast from very high purity elements were investigated by positron …

We report here on hydrogen-vacancy interactions in high purity aluminum by employing
positron annihilation spectroscopy (PAS) analysis of hydrogen-loaded samples, aiming to …

Abstract Effects of microalloying with Ag on the precipitation process in an Al–Cu–Mg alloy
with high Mg: Cu ratio have been investigated during artificial ageing of the ternary and …

Vacancy and solute atom clusters of various sizes and number densities may be formed in
Al alloys during natural ageing (NA) after solutionising and quenching. We study the …

We investigate the artificial aging process of the weldable Al-alloys AA-6013 (AlMgSiCu)
and AA-6061 (AlMgSi) by positron annihilation spectroscopy and Vickers micro-hardness …

The clustering kinetics in quenched pure Al, binary Al–Mg and binary Al–Si alloys were
studied by positron annihilation lifetime spectroscopy (PALS) and differential scanning …

Electron-positron momentum distributions measured by the coincidence Doppler
broadening method can be used in the chemical analysis of the annihilation environment …

Adding trace elements (Cd, In, Sn) to Al‐Cu‐based alloys can significantly improve their
strength by the growth of small and finely distributed θ′ precipitates. However, the …

Abstract We study Al-1.74 at.% Cu as a typical binary model alloy to obtain new information
on the precipitation sequence. The alloy has been solution heat treated, rapidly quenched …

Aluminium-copper alloys of the 2xxx type receive their excellent mechanical properties by
the formation of copper-rich precipitates during hardening. Size, distribution and crystal …
