“…In a study done to compare the effects of different peening methods on austenitic stainless steel SUS304, it was found that grain boundary hardening and dislocation hardening are the most important mechanisms [23]. Moreover, it was reported that fatigue loading reduces the compressive residual stress introduced by peening and that the reduction depends on the particular surface treatment employed [24][25][26].…”

The traditional technique used to modify the surface of a metallic material is shot peening; however, cavitation peening, a more recent technique in which shot is not used, was developed, and improvements in the fatigue strength of metallic materials were demonstrated. In order to compare the fatigue properties introduced by shot peening with those introduced by cavitation peening, crack initiation and crack growth in specimens of austenitic stainless steel (Japanese Industrial Standards JIS SUS316L) treated using these techniques were investigated. With conventional cavitation peening, cavitation is produced by injecting a high speed water jet into water. In the case of submerged laser peening, bubbles are generated using a pulsed laser after laser ablation, and the impact produced when the bubbles collapse is larger than that due to laser ablation. Thus, in this study, cavitation peening using a water jet and submerged laser peening were investigated. To clarify the mechanisms whereby the fatigue strength is improved by these peening techniques, crack initiation and crack growth in specimens with and without treatment were examined by means of a K-decreasing test, where K is the stress intensity factor, and using a constant applied stress test using a load controlled plane bending fatigue tester. It was found that the improvement in crack initiation and the reduction in crack growth were roughly in a linear relationship, even though the specimens were treated using different peening methods. The results presented here show that the fatigue strength of SUS316L treated by these peening techniques is closely related to the reduction in crack growth, rather than crack initiation.

“…As stated in [8] at such high value of M d30 austenite phase is very unstable. Authors in [9] shows X-ray difractogram after a deep rolling of 304L steel, which according to α'(110)/ γ( 111) ratio can be classified in group (iv), and estimated the martensitic volume fraction on 27,5%. Similar results are obtained from Altenberger and all [10] after deep rolling.…”

Abstract. In this paper, experimental results about hardness and phase composition of surface layer of AISI 304L SS, machined by using ball burnishing process, conducted under a new kinematic scheme, are presented. The effect of different combinations of the process regime parameters on the amount of strain induced martensitic phase, is discussed. The amounts of austenitic and strain induced martensitic phases are identified by x-ray diffractometer. Micro hardness along the depth of the hardened layer is measured. Conclusions about the influence of the ball burnishing process on strain induced martensitic phase are given.

“…Mechanical surface treatments, e.g. shot peening, deep rolling or laser shock peening are well-known processes for fatigue life enhancement due to the generated near-surface work hardening layer and compressive residual stresses retarding the fatigue crack initiation and propagation [9][10][11][12][13][14][15]. However, the beneficial effects of mechanical surface treatments can be deteriorated under high loading and/or high temperature.…”

The deep rolling process can be modified by annealing at appropriate temperature and time to optimize the fatigue performance of metallic materials. The hardening process of the martensitic stainless steel AISI 440C composes of quenching and double tempering processes. We suggest to integrate the deep rolling process into the hardening treatment because the heat from the tempering process possibly provides sufficient static strain ageing effects. It was found that the deep rolling process can be integrated fully into the hardening process of the martensitic stainless steel AISI 440C, especially in the middle of the double tempering processes. The heat of the tempering process after the deep rolling process leads to beneficial static strain ageing effects as a consequence of greater fatigue lives. Moreover, the maximum fatigue life was detected in this research, when the optimized annealing had been performed instead of the second tempering process.
