Abstract Stress-strain curves of slowly cooled and/or quenched Al-4.5 wt.% Mg alloy samples were studied in the temperature range from 473 K to 553 K. Two main temperature regions of relaxation have been found, a low temperature region (below 493 K) and a high temperature region (above 513 K); a transient region lies between these temperatures. The parabolic work hardening coefficient, the fracture time, the yield stress and the fracture stress of annealed and quenched samples have been found to decrease with increasing deformation temperature and to exhibit minimum values at 493 K. The X-ray analysis of the slowly cooled and quenched samples has shown that the lattice parameter a of the aluminium matrix reaches a minimum value at 493 K.
