Аннотация
The effect of homogenizing on the microstructure and properties of Al–Mg–Si roll-casting sheet were investigated by optical microscopy, scanning electron microscopy, energy dispersive spectroscopy, Vickers hardness measurements, and conductivity testing in this paper. The morphology, quantity, and species of the phases were studied. The results show that the Mg2Si dissolved completely and Al5(FeMnCr)Si transformed into Al74(MnFeCr)20Si6 phase during homogenization. And the wavy grain boundaries that existed in the roll-casting microstructure vanished. After homogenization at 550°C × 4 h, the sample hardness reduced to 54 HV and conductivity increased to 26 MS/m.
