1987/1/1· The effect of stress and temperature on the steady state creep rate of SiCw/2124 Al (T4) has been determined. The stress exponent for steady state creep of the composite is shown to increase from a value of 8.4 at 177 °C to a value of 21 at 288 °C. The activation energy for creep was determined to be 277 kJ/mol for testing in the temperature range from 149 to 204 °C and 431 kJ/mol for

Effect of Creep Damage on the Tensile Creep Behavior of …

Creep deformation in the siliconized silicon carbide below the threshold stress for creep damage was determined to be controlled by disloion processes in the silicon phase. At applied stresses above the threshold stress for creep damage, creep damage enhanced the rate of deformation, resulting in an increased stress exponent and activation energy for creep.
