Papers by Keyword: AA1050 Ingot

Abstract: A description of positron annihilation spectroscopy (PAS) in solids is given in terms of a trapping model. Data are presented for a commercial AA1050 dilute alloy ingot, and fitted to a model allowing presentation in the form of Arrhenius plots. From whence the value of the activation enthalpy, , for thermal vacancies obtained by PAS for AlFeSi is found to be 0.860.18eV.
