摘要：

The high-temperature creep behavior of Al-Cu-Mg alloy was studied by the constant-stress uniaxial tensile creep experiments under the temperatures of 473 K, 503 K and 533 K. Constitutive models for describing the high-temperature creep behavior of Al-Cu-Mg were established based on the theta projection method. The material parameters of the established constitutive models are associated with applied creep stress and temperature. Results show that a good agreement between the experimental and predicted results is obtained, which confirms that the established creep constitutive models can give an accurate and precise estimate of the high-temperature creep behavior for the studied Al-Cu-Mg alloy. Additionally, the specimens at 533 K failed by the intergranular creep fracture. (c) 2012 Elsevier B.V. All rights reserved.
