“…Accordingly, the volume fraction of martensite in the SMAT samples increases at lower temperatures [24][25][26]. Although no definitive explanation was given for the influence of martensite (α') prior to the cyclic loadings [27], its presence is usually reported to be beneficial regarding tensile strength [28]. Also, for a given SMAT processing condition, the use of cryogenic temperature was shown to decrease the surface roughness [25,26], a modification that may result in improved fatigue performance.…”

The potential of ultrasonic surface mechanical attrition treatment (SMAT) at different temperatures (including cryogenic) for improving the fatigue performance of 304L austenitic stainless steel is evaluated along with the effect of the fatigue loading conditions. Processing parameters such as the vibration amplitude, the size, and the material of the shot medias were fixed. Treatments of 20 min at room temperature and cryogenic temperature were compared to the untreated material by performing rotating–bending fatigue tests at 10 Hz. The fatigue limit was increased by approximately 30% for both peening temperatures. Meanwhile, samples treated for 60 min at room temperature were compared to the initial state in uniaxial fatigue tests performed at R = −1 (fully reversed tension–compression) at 10 Hz, and the fatigue limit enhancement was approximately 20%. In addition, the temperature measurements done during the tests revealed a negligible self-heating (∆t < 50 °C) of the run-out specimens, whereas, at high stress amplitudes, temperature changes as high as 300 °C were measured. SMAT was able to increase the stress range for which no significant local self-heating was reported on the surface.

“…During deformation, these steels can exhibit two mechanisms of strain hardening: martensitic transformation, also known as transformation-induced plasticity (TRIP), or twinning, which is referred as twinninginduced plasticity [1]. The strain-induced martensitic transformation in metastable austenitic stainless steels, such as AISI 304 and 321, is a well studied phenomenon under monotonic [2][3][4] and under cyclic loading [5][6][7][8][9][10][11][12]. The investigations revealed a considerable difference in the fatigue life between the strain-controlled and stress-controlled tests.…”

Abstract. Total strain-controlled low-cycle fatigue tests were performed at room temperature on a high alloyed metastable austenitic stainless cast steel in the range of 1x10 -3 ≤ Δ t/2 ≤ 3x10 -2 at constant strain rate of 4x10 -3 s -1 . The cyclic stress response revealed combinations of cyclic hardening, saturation and cyclic softening, depending on the applied cyclic total strain amplitude. Total strain amplitudes higher than 8x10-3 result in a pronounced secondary hardening up to fracture. In the case of metastable austenitic steels, at higher strain amplitudes the secondary hardening is an indicator for the austenitic-martensitic transformation. The deformation-induced α'-martensite content was detected using a nondestructive magnetic measuring technique (feritscope). The microstructure was investigated for different total strain amplitudes applying optical and scanning electron microscopy (SEM). It could be observed that with an increasing total strain amplitude the deformation band density increased considerably.

“…The generation of intracrystal martensite makes the material brittle. 22 The formation of intergranular martensite is equivalent to wrapping a hard shell on grains 15 . The transformation of austenite to martensite during cyclic test at room temperature is plastic strain-induced martensitic transformation.…”

The effect of tensile and torsional prestrains on fatigue lives of 304 stainless steels is compared. The fatigue life as a function of prestrain amplitudes exhibits an ‘S’ curve, and the inflexion point of the S curve is affected by prestrain modes and cyclic strain amplitudes. An interesting phenomenon is that when the onset stress of secondary hardening reaches 300 MPa, intergranular martensite begins to be formed. Combining martensite distribution, fatigue life and cyclic stress responses, the onset stress of secondary hardening is proposed to reflect the location of martensite nucleation sites. Compared with tensile prestrain, torsional prestrain results in higher stress. In addition, higher prestrain and cyclic amplitudes also lead to higher cyclic stress and hence earlier nucleation of intergranular martensite. Furthermore, the influence mechanism of prestrain modes and cyclic strain amplitudes on the inflexion point of S curve is revealed.
