The microstructure of cast alloy Al – 8.88% Si – 3.38% Cu is studied after isothermal hardening at 65°C for 1 – 90 min using light microscopy, X-radiography, and a scanning electron microscope with energy dispersion analysis. After isothermal hardening alloy is aged at 525°C. The duration of isothermal exposure is established in order to obtain high alloy hardness.
