| Popis: | In producing cold-deformed patented wire an increase of total strain and ultimate strength o B results initially in a linear increase of fatigue strength whereas at high strains the rate of increase of this parameter greatly decreases. In the range of the linear dependence the endurance limit o_ I of wire increases with a reduction of the carbon content of the steel whereas its maximum value is almost independent of the carbon concentration. On the basis of the analysis of possible mechanisms responsible for these relationships it is possible to recommend [i] a number of methods of increasing the fatigue strength of colddeformed wire. Specifically, tempering under stress (TS) should greatly increase the endurance limit of wire (the effect is strongest in the region of the linear dependence of 0_ I on o B) and weaken the effect of the carbon content. |
