摘要：

The effect of heat treatment on both microstructures and performances of semisolid Al-5Fe-4Cu alloy was investigated with scanning electron microscopy (SEM), transmission electron microscopy (TEM), differential scanning calorimetry (DSC) and X-ray diffraction (XRD) and tensile test. The results showed that the semi-solid Al-5Fe-4Cu alloy's response to the solution heat treatment (SHT) is abnormal compared with the conventional semi-solid Al alloys, i.e. the tensile properties of the semi-solid Al-5Fe-4Cu alloy decreased significantly after SHT. Nevertheless, the semi-solid Al-5Fe-4Cu alloy subject to direct ageing without SHT could exhibit conspicuous improvement of the tensile properties. And, the reason of the abnormal results has been analysed and discussed in detail.
