“…(Mg2Si), S' (A^CuMg), and the quaternary phase AlMgSiCu which is designated as Q (AlsMggSiôC^) or X (AlsMggSisC^). 53 ' 54 It is imperative to mention here that the precipitation-hardening characteristics of Al-Cu-Si-Mg alloys are sensitive to the Cu/Mg and Mg/Si ratios as well as to the total solulc content ui llie alluy. llic prujcuuun ui Icutuicuioii plictsc iiclus, sllowii in Figure 2.6, was proposed for the identification of the equilibrium phases which may exist in Al-Si-Cu-Mg alloys.…”

“…Quantification of precipitation hardening therefore requires detailed knowledge of the evolution of precipitate size and fraction during ageing. There has been extensive work on precipitate type identification and size measurement [1][2][3][6][7][8], whereas little information is available on quantification of the precipitate fraction in aluminium alloys. In a recent study, a method was proposed to estimate the fraction of precipitates of nanometre scale in C250 maraging steel and has demonstrated promising results [9].…”

“…[40,41] The delay in time on the yield strength in alloy 319 is irrelevant as natural aging in this alloy takes place at a lower rate. [42] DAS exerts an important influence on the tensile strength of peak-aged alloys (356 and 319) (Figure 12), and this effect can be explained in terms of the size and shape of the magnesium-and copper-rich particles that require more time to dissolve as they coarsen. [8,[30][31][32][33] Ductility, which is expressed in terms of the total elongation in the tensile test is strongly affected by the increase in DAS, which can be attributed to the increase in porosity in the material as the solidification rate is reduced.…”
