MECHANICAL AND THERMAL PROPERTIES IN AS-CAST Al-Zn-Mg-Cu(-Sc-Zr) ALLOYS

Abstract

The aim of the work is to study mechanical and thermal properties and microstructure development of as-cast Al-Zn-Mg-Cu-(Sc-Zr) alloy during the non-linear annealing. The apparent activation energies of the observed processes were also calculated.
