TLDR
In this paper, low cycle fatigue studies have been carried out on 2 wt% Mn, 2wt% Si and 0.1 wt % C steels with dual-phase and tempered martensitic structures.Abstract:
Low cycle fatigue studies have been carried out on 2 wt% Mn, 2 wt% Si and 0.1 wt% C steels with dual-phase and tempered martensitic structures. Fatigue crack initiation and propagation were investigated using scanning electron microscopy as well as optical microscopy. In addition, taper-section and cross-section techniques were also performed for more detail studies on the correlation of crack initiation with the internal microstructures of the testing samples. Internal microstructures were also investigated on the dual-phase steel sample before and after fatigue fracture by transmission electron microscopy.read more

The dependence of some tensile and fatigue properties of a dual-phase steel on its microstructure
Xue-Ling Cai,J. Feng,W. S. Owen +2 more
TL;DR: In this article, five different dual-phase microstructures have been produced in a steel containing 0.11 C, 1.60 Mn, 0.73 Si and they were characterized by measurement of the mean ferrite path and the density and distribution of the extrinsic transformation accommodation dislocations in the substructure of the ferrite.

Cyclic stress strain relations and strain-controlled fatigue of 4140 steel
TL;DR: The strain controlled low cycle fatigue properties and cyclic stress-strain response of a 4140 steel were investigated as functions of tempering temperature in this paper, and it was suggested that the endurance limit is essentially equal to the cyclic yield stress.

Thermal cycling treatments and microstructures for improved properties of Fe-0.12% C-0.5% Mn steels
J.Y. Koo,Gareth Thomas +1 more
TL;DR: In this paper, a non-standard heat-treating process has been successfully applied for improving the mechanical properties of low carbon Fe 0.12% C-0.5% Mn steels, where the process consists of alternate thermal cycling in the γ range and two phase (α + γ ) range with intermediate quenching so as to produce a microduplex fine grained mixture of martensite and proeutectoid ferrite.
