Özet:

 

The propose of the present work is to study the interaction of  positrons with quenched-in defects and clustered atoms to estimate  formation enthalpy in series 50xx of commercial Al-Mg alloys, namely,  5049, 5051,5052 and 5083 at various concentrations: 1.9, 2.09, 2.46  and 4.44 wt % of Mg, respectively.  Typically additional impurities  were mainly Si, Fe, Cu, Cr and Ti.  The monvacancy formation energy of  Al-Mg alloys was measured from a trapping model analysis of the  T-dependence of the positron lifetime.
