Effect of pre-aging conditions on T5 heat treatment behavior of Al-9.0%Si-0.3%Mg die-casting alloy was investigated by using hardness measurement, differential scanning calorimetric analysisDSCand transmission electron microscopy TEM. T5 treated alloy showed the positive effect on the two-step aging at pre-aging temperatures between 273 and 343 K, unlike T6 treated alloy which showed the negative effect at pre-aging temperatures below 343 K. The positive effect on two-step aging seems to be the characteristic behavior at T5 heat treatment. Difference of two-step aging behavior between T5 and T6 treatments seems to result from the difference of cluster1formed in the pre-aging process below 343 K. Higher water-quenching temperature after casting tended to increase the hardness after artificial aging.
