The Effect of Natural Ageing Heat Treatment on the Mechanical Properties of the AlZn4.5Mg1 Alloy

Résumé

In this paper, the influence of the time of artificial aging on the variation of the values of the mechanical properties of AlZn4.5Mg1 alloy was studied.
By applying the thermal processing variant described in the paper, an increase in the values of the resistance properties was obtained as the natural aging time increases to the value of 1080 hours. Above this value of the natural aging duration the values of the properties of mechanical strength record a decrease.
