“…Thus, adding Ag into Al-Mg-Cu alloy changes the phase formations conditions and slows down the degradation of the alloy at elevated temperatures levels [ 20 ]. The crystallographic orientation and chemical composition of Al-Cu-Mg alloys is affected by the addition of silver in the range of about 0.5% through artificial ageing, which improves the phase precipitation rate [ 20 , 21 , 22 , 23 , 24 ].…”

The present investigation deals with a comprehensive study on the production of aluminum based alloys with the incorporation of different alloying elements and their effect on its electrical conductivity and mechanical properties. Casting of pure aluminum with different concentration and combinations of alloying additives such as cupper (Cu), magnesium (Mg) and silver (Ag) were carried out using a graphite crucible. The as-cast microstructure was modified by hot rolling followed by different heat-treated conditions viz., annealing, normalizing, quenching, and age hardening. The mechanical properties and electrical conductivity of the produced heat-treated alloys sheets under various processing conditions were carried out using tensile testing, hardness, and electrical resistivity measurements. It was found that by increasing the alloying elements content, yield strength results increased significantly by more than 250% and 500% for the as rolled and 8 h aged Al-Cu-Mg alloy, respectively. On the other hand, the electrical conductivity reduces slightly with −14.6% and −16.57% for the as rolled and 8 h aged of the same Al-Cu-Mg alloy, respectively.

“…It is known that the addition of silver to the Al-Cu-Mg alloys, providing the Ω'-phase formation during artificial aging, improves mechanical properties of semi-finished products and helps to increase its heat resistance, fracture toughness and other characteristics [7][8][9]. Thus, VIAM developed such new alloys as V-1167 and V-1213 (similar to the use of 1163 and AK4-1ch alloys) [10,11].…”

The influence of artificial aging on the phase composition and the properties of sheets made of V-1213 alloy of Al-Cu-Mg-Ag system. It is shown that the phase composition, morphology, dispersion and the density of phase discharge changes with the temperature increase of artificial aging. After the aging at the highest temperature in the range from 150 to 190 °C the maximum density of S' and Ω' phase is observed. This density provides the best combination of mechanical properties when extended at room temperature and high temperature strengthcharacteristics.

“…Alexopoulos et al 75 studied the effect of aging temperatures on the yield strength of Al-Cu-Mg alloy, and the result showed that the yield strength of the alloy decreased by 6 MPa as the artificial aging temperature increased by 10 ℃ within the range of 170 ℃ and 210 ℃, indicating that excessively high heat treatment temperatures lead to coarsening of precipitates and reduced yield strength of the alloy. Moreover, Teleshov et al 76 also demonstrated that increasing the aging temperature results in coarsening of Ω phase in Al-Cu-Mg-Ag alloys, decreasing the number density of c and, thus, reducing the mechanical properties of the alloy at room temperature. Therefore, it is necessary to select the appropriate artificial aging temperature to obtain the optimum mechanical properties of the alloy.…”
