Impact of the artificial ageing time on the strength and electrical resistivity responses of an AA 6082 aluminum alloy

The aim of this work was to produce a material with high mechanical properties and electrical conductivity. To reach these objectives, the influence of artificial aging treatments on hardness, electrical conductivity and fatigue resistance of AA6082 aluminum alloy was investigated and the detailed artificial aging parameters were proposed. Electrical conductivity of materials was measured by the four-point method and the microstructure of the precipitates were o by optical microscopy then quantitatively investigated with the aid of an image analysis Toup View Software. Moreover, the influence of the proposed heat treatment on the conductivity, microhardness and fatigue resistance of the tested specimens was compared.
