Creep-Rupture Properties of Aluminum Alloy A356-T61
Permanent-mold test bars of aluminum alloy A356.0-T61 were subjected to elevated-temperature tensile tests and isothermal constant-load stress-rupture tests (for lives up to 10 000 h), under the aegis of the Metal Properties Council. Rupture strength and secondary creep rate data were analyzed by the successive plotting of isotemperature and isotime curves and by the Larson-Miller procedure. A reasonable base for setting allowable stress values for design codes has been developed.
