Strain ageing of steel was first observed during the 19th century when the maximum load carrying capacity of a test piece was increased after it had been retested after a previous series of testing in the plastic range.
General acceptance has been recognized that strain ageing is due to the DIFFUSION of CARBON and/or NITROGEN ATOMS in solution to dislocations that have been generated by plastic deformation however the resulting characteristics are the result of a complex series of metallurgical reactions.
