The Influence of Subzero Rolling on the Tensile Properties of Commercially Pure Titanium
Commercially pure titanium was rolled at room temperature and -105, -240, and -320 F for various amounts of reduction to 40 percent. Tension tests of these cold-worked materials were performed from room temperature to -320 F. Increased strength with increased retained true strain at fracture was obtained by selected deformation-temperature cycles. Log-log plots of the flow data of the starting material showed two segments differing in slope, rather than one straight line as predicted by the power law. The strains at which the inflection occurred decreased with decreasing testing temperature, while increasing amounts of reduction and decreasing rolling temperatures moved these points of inflection to higher strains. The inflection points are attributed to a change in deformation mechanisms from slip to twinning. The slopes of the two segments also decreased with both increasing reductions and decreasing rolling temperature. (Author)
