High strength, good ductility, and superior fatigue behavior were produced in fully pearlitic steel by thermomechanical treatments (TMT) in which heavy amounts of cold rolling were followed by rapid annealing above the A 1 temperature. Alignment of the cementite fibers in a soft ferrite matrix by TMT gives a number of beneficial effects on mechanical behavior without the brittleness inherent to cold rolling alone. A linear regression equation was developed to quantitatively relate prior austenite grain size and interlamellar spacing with the yield strength. TMT involving lower annealing temperatures for short times resulted in optimal fatigue behavior relative to both random coarse pearlite and 75 pct cold rolled pearlite. This superiority was manifested by higher fatigue ratios (stress at 107 cycles/UTS) and higher S/N curves normalized with respect to either UTS or hardness. Transverse samples showed better fatigue strength than longitudinal ones because of anisotropy in both mechanical fibering of the microstructure and in the crystallographic texture of the ferrite matrix.
