“…High threshold values in DP steels are due to the crack tip shielding effects caused by the crack deflection and constraining of plastic deformation in ferrite. It has been reported that DP steels have the highest threshold values among metallic materials (Ref [1][2][3][4][5][6]. Crack deflections in the ferrite, ferrite grain boundaries, and ferrite/martensite interfaces result in crack closure effects ( .…”

Dual-phase (DP) steels with different martensite contents were produced by subjecting a low carbon steel to various heat treatment cycles. In order to investigate the effect of dynamic strain aging (DSA) on mechanical properties, tensile specimens were deformed 3% at 300°C. Room temperature tensile tests of specimens which deformed at 300°C showed that both yield and ultimate tensile strengths increased, while total elongation decreased. The fatigue limit increased after pre-strain in the DSA temperature range. The effects of martensite volume fraction on mechanical properties were discussed.
