摘要：

Tensile creep tests were conducted on an extruded and age-hardened Al-Cu-Mg-Ag alloy using constant load at 150, 180 and 210 degrees C. The normal three-stage creep was observed with a well defined steady state. The values for the stress exponent were between 11 and 15 for the temperatures and the activation energy for creep was about 152 kJ mol(-1). The results obtained in this investigation were compared with those on some other Al-Cu-Mg-Ag alloys. (C) 1997 Elsevier Science S.A.
