The investigation and study of the yield point phenomenon and strain aging in low carbon stell began in 1935, with the work of Danvenport and Bain. They described the appearance of "stretcher strains" during the deformation of rimmed low carbon steel in the annealed condition. In describing the tensile properties of such a material, they noted that the abrupt, localized elongation may reduce the load as much as 15 per cent below the upper yield point. In their studies of strain aging, Davenport and Bain used penetration hardness to follow the progression of the aging.
