Abstract

The influence of preaging at room temperature on the artificial aging of an aluminum alloy with 1. 4% Mg//2Si and varying amounts of Fe was investigated by mechanical property determinations. An unfavorable effect was caused by increase in the stability of the G. P. zones formed at room temperature. The minimum observed in the yield strength vs age hardening curve is explained by the difference in stability of the zones arising through two different mechanisms. The age hardening process has no significant influence on the development of the tensile strength. Elongation is reduced by age hardening since the elastic limit gradually approaches the tensile strength. The mechanical properties were not significantly affected by iron additions up to 0. 25%.
