Effect of severe plastic deformation on creep behaviour of a Ti-6Al-4V alloy

Original language description

This paper examines the effect of severe plastic deformation on creep behaviour of a Ti-6Al-4V alloy. The processed material with an ultrafine-grained (UFG) structure (d a parts per thousand 150 nm) was prepared by multiaxial forging. Uniaxial constant stress compression and constant load tensile creep tests were performed at 648-698 K and at stresses ranging between 300 and 600 MPa on the UFG processed alloy and, for comparison purposes, on its coarse-grained (CG) state. Creep behaviour was also investigated by nanoindentation method at room temperature under constant load. The results of the uniaxial creep tests showed that the minimum creep rates of the UFG specimens are significantly higher in comparison with those of the CG state. The CG alloy exhibits better creep resistance than the UFG one over the stress range used. The indentation creep tests showed that annealing had little effect on the creep behaviour in UFG Ti alloy at room temperature.
