To investigate the high-temperature thermomechanical properties of the aluminum alloy AlSi<SUB>10</SUB>MnMg (AA365), a high-temperature tensile test was conducted over a wide range of temperatures (273 K to 773 K). The tensile strength of the AA365 alloy decreased from 299 MPa to 10 MPa as the temperature increased. The tensile strain increased from 12.4 % at 273 K to 44.6 % at 673 K. The microstructural observation showed that the effect of intermetallic compounds increased rapidly with the increase in temperature. This effect led to the strengthening effect caused by disturbing the dislocation movement and was considered as the reason for the increase in yield strength. A sudden decrease in tensile strength was caused by re-dissolution of secondary phases owing to the increase in temperature near the melting point. Through the fractography analysis, it was revealed the mechanism of rapid fracture occurred by the micro-cavities induced ductility failure.
