FATIGUE PROPERTIES OF COLD-ROLLED SHEET STEELS

Fatigue characteristics of representative cold-rolled, high strength steels, in gases ranging from 0.072 in. (1.83 mm) to 0.055 in. (1.39 mm), were determined in fully reversed, axial strain cycling at amplitudes up to 0.01. Alloys were selected from three families of high strength steels: recovery annealed steels, conventional microalloyed steels-- nitrogenized steel and rephosphorized steel, and dual phase steel. Cold rolled low-carbon steel provided a comparative baseline. Cyclic stress-strain curves are presented to indicate the degree of cyclic stability achievable by various strengthening mechanisms while relative fatigue resistance is determined from strain-life curves. The implications of these behavioral trends to component down gaging are discussed.
