Creep tests at room temperature under combined tension-torsion have been performed on thin walled tubes of commercially pure aluminium (ElA) in the annealed, extruded and prestrained conditions. The required creep stresses were achieved by incremental loading along a constant stress ratio path (radial loading). Axial ([epsilon][sub]zz) and shear ([gamma][sub][theta]z) strains were measured throughout deformation. Strains produced by radial loading on annealed and extruded aluminium consisted of an instantaneous component and a short-time creep component. For all stress paths the latter component was the form [epsilon][alpha]t[sup]m where the time exponent m lay in the parabolic range [omicron]
