Effect of Ag content and heat treatment on the stress corrosion cracking of Al–4.6Cu–0.3Mg alloy

Impact of Cu/Mg Ratio on Thermal Stability of Hot Extrusion of Al-4.6 Pct Cu-Mg-Ag Alloys

“…The table also shows the tensile test result of the standard cast A201 alloy under the same heat-treatment conditions. [39] This result is consistent with the results of the hardness test, which reveal that the tensile strength of an alloy with a low Cu/Mg ratio is high, and that those of alloys B and C are higher than that of the cast A201 alloy. Additionally, the strains of hot-extruded alloys A, Fig.…”

“…The first points at the beginning of the curve were the hardness of alloys tempered to the T7 condition. [39] B, and C evidently exceed that of the cast A201 alloy. A hot-extrusion process elongated the grains and eliminated the defects in the alloy, increasing the elongation and tensile strength of the alloy.…”

Effects of Cu/Mg ratio and heat treatment on microstructures and mechanical properties of Al–4.6Cu–Mg–0.5Ag alloys

“…3(b) and (c) diffraction patterns. The angles between the long axes of the indicated U and q 0 phases in the TEM bright images are in accordance with those measured in detailed analyses of similar alloys exhibiting the same U and q 0 precipitate/matrix orientation relationships, as performed by Ringer [11] and Chang [21]. Alloy BT7 has denser U but less q 0 phase than alloy AT7.…”

Modelling the constitutive behaviour of aluminium alloy B206 in the as-cast and artificially aged states

“…Samples were initially solution treated at 515 • C for 2 h followed by an 8 h treatment at 525 • C [18], and then artificially aged at 4 distinct temperatures, 150, 175, 200 and 225 • C, for 5 time periods, 1, 2, 5, 10 and 24 h. Tensile tests were performed on cylindrical samples 4 mm in dia. and 19 mm in gauge length using a 50 kN Instron 5969 tensile tester.…”
