The precipitation and dissolution in heat-treatable aluminum alloys was studied by using differential scanning calorimerty (DSC). It is very sensitive and efficient to show the minute heat changes during the precipiation of the phase transformation by using DSC. From the DSC data, the precipitation kinetics of Al-Si-Mg alloys can be analyzed and also the effect of alloy elements on the precipitation of the strengthening phase of β'-Mg2Si can be realized.
