Resumen:
The effects of dynamic strain aging (DSA) on the cyclic mechanical behaviorwere investigated in a ferritic
steel type AISI 430F. Strain-rate changes performed during cyclic tests showa negative strain-rate dependence
of the flow stress for temperatures ranging from 200 ◦C to 450◦C. Low-cycle fatigue curves exhibit
prominent cyclic hardening at 400 ◦C and 450 ◦C. The influence of the embrittlement phenomena on the
hardening of this ferritic steel was also investigated by performing aging treatments at 400 ◦C and 450 ◦C
in the alloy. These results suggest that a DSA mechanism is operative in this material in a temperature
range between 300 ◦C and 400 ◦C. Stress relaxation experimental results are also discussed in terms of
dynamic strain aging.
