Effect of Heat Treatment on Fatigue Behavior of (A193-51T-B7) Alloy Steel
نویسنده
چکیده
This research comprises a study of the effect of heat treatment on fatigue behavior of (A193-51T-B7) alloy steel. Two heat treatment processes were conducted, namely, annealing and quenching followed by tempering at 200C. All fatigue tests were carried out using a rotary bending machine with constant stress ratio, R=-1. The eddy current probe was used to measure the crack length propagation. From the obtained results, it was found that fatigue crack growth rate of the quenched and tempered specimens is lower than that of the standard specimens. While the fatigue crack growth rate of the annealed specimens is higher than that of the standard specimens.
