“…In both studies, they reported that after 2•10 6 cycles, the fatigue limit was around 400 MPa. Furthermore, TWIP steels deformation mechanisms as well as their fatigue behavior under low cycle fatigue conditions have been studied during the last years by several research groups [8,9,10,11,12,13]. Recently, Niendorf et al [14] investigated the influence of pre-deformation and also the presence of notches on damage initiation of commercial high manganese steel under high cycle fatigue conditions.…”

Twinning Induced Plasticity steels exhibit a high strain hardening rate which translates into a remarkable combination of ductility and strength. A thorough experimental approach was performed by advanced characterization techniques to study the deformation mechanisms developed under high cycle fatigue conditions. Results clearly lay out that the cumulative strain damage leads to strengthening but also induces microcracks at the intersection of twin boundaries which promote fracture.

“…A number of works have been devoted to the studies on composites where the TRIP/TWIP matrix has been hardened with Zr and Al oxides to achieve a higher ultimate strength [32][33][34]. So, a composite based on high-alloy TRIP steel hardened with ZrO 2 particles, owing to the interaction at the boundaries of the components, makes it possible to obtain an increase in a set of strength and plastic properties compared to the initial materials [35,36], an increase in the absorbed impact energy [37] and an increase in the fatigue strength [38].…”

A review of the published data concerning the structural features of TRIP/TWIP steels, the relationship thereof to mechanical properties, and the relationship between strength parameters under static and cyclic loading is presented. It is shown that the level of mechanical properties of such steels is determined by the chemical composition and processing technology (thermal and thermomechanical processing, hot and cold pressure treatment), aimed at achieving a favorable phase composition. At the atomic level, the most important factor is represented by stacking fault energy, the level of which is decisive in the formation of austenite twins and/or in the formation of strain martensite. By choosing the chemical composition, one can set the level of stacking fault energy corresponding to the required mechanical characteristics. In the case of cyclic loading, an important role is played by the strain rate and the maximum load in the course of testing. So, at a high loading rate and a load approaching the yield strength under tension, the intensity of twinning processes and the rate of formation of martensite increases. It has been shown that one of the relevant ways to further improving the structural and functional properties of TRIP and TWIP steels consists in developing composite materials based on them. At present, surface modification and coating application, especially by means ion-vacuum methods, can be considered the most promising direction for making such composites.

“…Metal Matrix Composites (MMC) have been under investigation over the last decades and showed enhanced mechanical properties in terms of strength, stiffness and wear resistance compared to the unreinforced material [1]. Moreover, the fatigue properties were observed as well, finding that the deformation behaviour of discontinuously reinforced MMCs was dominated by the volume fraction [2,3,4,5,6], size [2,7,8] and morphology of the particles as well as the strength of the metallic matrix [4,9]. In the most cases the latter consists of lightweight materials like titanium, aluminium or magnesium.…”

Metal Matrix Composites (MMC) based on a TRIP (TRansformation Induced Plasticity)- or TWIP (TWinning Induced Plasticity)-steel matrix reinforced with MgO-partially stabilized zirconia (Mg-PSZ) are an interesting research field as both components exhibit a deformation-induced or stress-assisted martensitic phase transformation and twinning, respectively. The present work deals with the fatigue characteristics of a reinforced CrMnNi-steel as a function of the ceramic particle size. Therefore, the particles were classified into three grades (grade 1: <10 μm; grade 2: 10-30 μm; grade 3: 30-50 μm) whereas the volume fraction concerning the composite material was kept constant at 10 vol.%. The composites were produced using the hot pressing technique. The tests were performed under total strain control in a range of 0.2% ≤ Δεt≤ 1.2%. The microstructure of fatigued specimens was examined using scanning electron microscopy.
