摘要：
The as-cast age hardening behavior of 356 cast alloy has been investigated by micro hardness measurement, differential scanning calorimetry (DSC), transmission electron microscope (TEM), and electron probe micro analyzer. Age hardening results show that micro hardness value after as-cast aging treatment is almost the same as by T6 treatment, and the solidification rate has little effect on the as-cast age hardening response of 356 cast alloy. DSC and TEM analysis results show that the as-cast age hardening response of 356 cast alloy is attributed to the precipitation of beta' and beta aEuro(3) phases, the high Si concentration in alpha(Al) contributes about 10 HV to the micro hardness value for samples in as-cast and as-cast aging conditions.
