“…Speich (1981) characterized these steels by a microstructure consisting basically of a ductile ferrite phase and high strength reinforcing martensite phases. Hashimoto and Pereira (1996) demonstrated that the ferrite phase is nucleated in the austenite grains boundaries. By quenching the austenite is transformed to martensite resulting in a microstructure composed by ferrite grains surrounding the martensite islands.…”

“…Crack deflections in the ferrite, ferrite grain boundaries, and ferrite/martensite interfaces result in crack closure effects ( . Although fatigue properties of DP steels have been investigated for many years (Ref [11][12][13][14][15][16], the effects of dynamic strain aging (DSA) on fatigue properties of DP steels with different martensite morphology have not been reported yet.…”

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.

“…It is based on the analysis of the thermal effects for the scatter and is applied on a dual-phase steel. This steel is used in the automotive industry that requires the knowledge of the fatigue properties and their scatter [17][18][19][20][21][22][23][24][25].…”

It is proposed to develop and identify a probabilistic two-scale model for HCF that accounts for the failure of samples but also for the thermal effects during cyclic loadings in a unified framework.The probabilistic model is based on a Poisson point process. Within the weakest link theory, the model corresponds to a Weibull law for the fatigue limits. The thermal effects can be described if one considers the same hypotheses apart from the weakest link assumption. A method of identification is proposed and uses temperature measurements to identify the scatter in an S/N curve. The validation of the model is obtained by predicting S/N curves for different effective volumes of a dual-phase steel.
