EXPERIMENTAL INVESTIGATION OF THE HEAT TREATMENT REGIMES FOR AK6 WROUGHT ALUMINUM ALLOY SHEET

Abstract

This paper conducted experimental study on determining mechanical properties and electrical conductivity of AK6 wrought aluminum alloy sheets after quenching and artificial aging. The results showed that, after plastic deformation, the AK6 alloy was subjected to quenching at temperature in the range of (510-520)^oC and artificial aging at 165^oC. Then, hardness, tensile strength and electrical conductivity of the alloy reached high values, meanwhile elongation was still maintained at a quite high value after aging for 9 hours. These values were about 134HV, 412MPa, 37.5%IACS and 16%, respectively. These results provide a scientific basic for application researches of AK6 aluminum alloy based on Al-Cu-Mg-Si-Mn system to manufacture mechanical products, especially in the field of defense production.
