Abstract:The possibility of changing the increment of solid solubility was investigated in Pb-added Al dilute alloy under the pressure of 5.4 GPa. The high-pressure treated specimens were analyzed with X-ray diffraction, optical microscopic and transmission electron microscopic techniques. Their material properties such as density, hardness, elastic modulus and electric resistivity were also measured. A noticeable increase in solubility was not observed contrary to a thermodynamical predication. Key Words:Al-Pb alloy, solubility limit, high-pressure treatment, immiscible
