“…Indeed, Nakayama et al [7] studied an alloy containing 0.138 at.% Sc aged at 250, 300 and 350 • C. But they normalized their measurements and did not specify the measuring temperature nor the corresponding pure Al resistivity, thus forbidding any use of their data. Drits et al [5] studied an alloy the Sc composition of which is larger than the Sc solubility limit and even the eutectic composition. Some primary Al 3 Sc precipitates may have appeared during the solidification and the alloy could not have been homogenized.…”

“…In Al-Sc alloys, such an increase of the resistivity in the beginning of the precipitation kinetics has never been observed experimentally [5][6][7][8][9][10]. Actually, it does not seem to exist in alloys where the solute is a transition element and the solvent a free electron like metal [20].…”

“…The aging response and precipitation strengthening in the postrolling heat treatment were examined and the impact of the solution parameters on age hardening are outlined. [18,19,21,84,[104][105][106][107][108][109][110].…”

“…Therefore, materials with the same peak value at a given aging temperature would have similar alloying element concentrations. Based on this principle, we compare the peak hardness obtained at 300°C in a series of the binary Al-Sc alloys reported in the literature [18,19,84,106,108,109] (Table 5.1), which is a normal cooling condition for permanent mold casting and direct chill (DC) casting. In such nonequilibrium conditions, the solute content of Zr after solidification is estimated around 0.15 wt.%.…”
