“…3) indicate that the formation of precipitates with different shapes 450 and sizes is not restricted to the cooling process. Precipitates of various shape were also found in other work after different ageing treatments [15,[43][44][45].…”

“…Thus, the rate of spheroidization is extremely rapid in modified alloys. Spheroidization and coarsening of the discontinuous phase occurs at elevated temperatures, 224 because the interfacial energy of a system decreases with the reduction in interfacial surface area per unit volume of the discontinuous phase. The reduction in interfacial energy is the driving force for the spheroidization and the coarsening processes which are also diffusion-controlled.…”

“…We have considered combating this accumulative hardening process by introducing high temperature anneals at intervals to induce coarsening of the silicon precipitate. Annealing experiments with solutiontreated-and-quenched Al-S1 alloys [66,67] and neutron irradiated aluminum [68] have shown that temperatures of 200°C or higher are required to ensure the appropriate coarsening in short times. A temperature of 200°C could be achieved from decay heat by reducing the hydrogen flow rate or the degree of refrigerator cooling.…”
