Abstract
Supersaturated Al-10 at%Si solid solutions were prepared by high-pressure and temperature techniques. The elastic constants, lattice constants, electrical resistivity, density and hardness of these obtained specimens were measured in each process of isochronal and isothermal aging. At isochronal temperatures of about 100°C°C to 300°C, rapid variations of several characteristics appeared, and the lattice parameters overshot that of pure aluminum. The relation between the Al-matrix and the precipitated phase of silicon and the activation energies for precipitation are also discussed.
