Al-Zn binary phase diagrams under pressures of 0.1 MPa and 2.1 GPa were experimentally determined mainly with the method of diffusion couple and the method of two-phase observation and analyses. The phase diagrams at 0.1 MPa and 2.1 GPa were also calculated with volumetric and thermodynamic data at 0.1 MPa. The results obtained from the calculations were compared with the experimental data.<BR>Solidus of the α phase and the β phase were observed to shift to the higher temperature range when the high pressure of 2.1 GPa is applied, and the solid solubility of the α phase decreases simultaneously. According to the values evaluated from the intersection point formed by the α phase solidus and the α/(α+β) phase solubility line, the maximum solubility of Zn in Al at 2.1 GPa is 68.1 at%Zn and the eutectic temperature is 750 K. These values are by 1.1 at%Zn and 96 K higher than those at 0.1 MPa, respectively. Based on the experimental results, it is proved that the top of the miscibility gap at 2.1 GPa rose to 702 K. This is 78 K higher than that at the 0.1 MPa. The calculated miscibility gap rises with the pressure and it exhibits the same trend as the experimental results.
