Abstract
A work-hardening correction has been added to a previously devised method for characterising the long-term deformation properties of metals and alloys by derivation from short-term relaxation data. The usefulness of this correction has been assessed by creep and stress relaxation measurements on titanium, copper and 70/30 brass. Within defined strain limits, good agreement is obtained between derived and directly measured creep parameters. The importance of the relaxation-system spring constant in determining the extent of the agreement is discussed.
