Cyclic deformation and fracture behavior, under total strain controlled low cycle fatigue (LCF) conditions, have been evaluated for 316(N) weld metal and 316L(N)/316(N) weld joint between 300-873 K. A peak in life has been observed at around 573 K. An anomalous stress response and drastic reduction in fatigue life concomitant with dynamic strain aging (DSA) has been observed between 573-823 K, in both weld metal and weld joint. Manifestations like decrease in half-life plastic strain and increase in half-life stress amplitudes and degree of hardening, reflected the occurrence of DSA. Weld metals have shown better fatigue life compared to weld joints.
