“…As shown in [16,17], cavitation resistance of stainless steels as being related to mechanisms of phase transformation and mechanical strength increment has been confirmed from different studies [20,[31][32][33][34][35]. Cavitation erosion resistance is shown to be mainly dependent on the localized surface elasticity and its work-hardening capacity in iron-based alloys [31,32].…”

“…In this case, the straininduced transformation of the austenite to ε(hcp)and/or α′(bcc)martensite lead the austenitic alloys erosion resistance to be enhanced [20] Microstructural refinement of thermomechanically treated 13Cr-4Ni MSS tends to result in longer incubation period when compared to non-processed steel [34]. On the other hand, the incubation time of ASSs can be correlated with the high-cycle fatigue resistance coefficient [35]. Finally, the growth of α′ fraction in ASSs tends to occur at the expense of the austenitic plastic zone, a result due to the dislocations interaction reducing the nucleation barrier for the martensitic transformation [36].…”

“…Additional microstructural aspects directly related to the work hardening of ASSs can also lead to a superior resistance to cavitation erosion [37]. The main aspects deserving attention are a smaller grain structure, alteration of the fraction of twin boundaries, and a favorable crystallographic orientation of the grains [35,[41][42][43].…”

In this work the behavior of the austenite phase at the surface of a low-carbon martensitic stainless steel and an austenitic stainless steel subjected to cavitation through ultrasonic vibration tests in liquid phase was studied. Emphasis was given to the behavior of two distinct types of austenite, in the case the reversed austenite of the as-tempered ASTM CA-6NM martensitic stainless steel, and the thermally-stable austenite of the solution-treated AISI 304 austenitic stainless steel. The evolution of phases fraction at the studied surfaces by XRD technique was characterized by two ways. Firstly, cavitation test intercalated with XRD measurements as a function of the test time was carried out. In the sequence, an indirect measurement technique comprising the use of Vickers indentation and controlled material removal by polishing, also intercalated with XRD characterization along the incubation period of both steels was used. This procedure was strong enough to determine the mechanism that precedes the erosive wear defining the incubation-acceleration stages transition and the cavitation-affected depth presenting γ(austenite)→α'(martensite) strain-induced transformation in the material microstructure, measured from the surface of the tested region into the interior of the substrate bulk of each studied steel. Such mechanism covers deformation of the steel matrix and strain-induced transformation of the austenite phase at the surfaces subjected to cavitation, strongly influencing the beginning of the significant mass loss process for both low-carbon stainless steels studied here.

There is frequent debate over the long-term stability of calibration specimens. It is an essential component of monitoring, especially for X-ray diffraction equipment used to determine residual stresses. If residual stresses are stable, a second consideration is that the residual stress should not be close to 0 MPa. If such specimens are available for monitoring, it is more sensitive concerning changes. These are key requirements when developing calibration specimens. In this study five specimens were observed, one of them was tested for more than 20 years. The stresses were determined with X-ray diffractometers. In the last four years two different X-ray methods for determination were used. It can be shown that high compressive residual stress does not change in steel if the specimens had no dynamic or static load and were stored under normal laboratory conditions. Article Highlights Finding a material in which compressive residual stress is stable Showing that the stability of compressive residual stress is over a long term The stability of the compressive residual stress is in a great range

“…This type of wear occurs for example in propellers [3], hydrofoils [4], pipe bends [5], pumps [6] and hydraulic machinery [7]. The collapse of millions of bubbles can generate fatigue fracture failure or a form of micro fatigue cracking [8][9][10]. Consequently, detachment of fragments of material occurs.…”

The phenomenon of cavitation erosion consists of the formation, growth, and collapse of bubbles in liquid media. The bubbles are responsible for the damage generated to metal and non-metal materials. Consequently, there is a pronounced degradation on the material surface, producing a scar in the impact area of the bubbles, and eventually the detachment of material. This experimental work aims to determine the performance of AISI 304 stainless steel base and coated with SiC. The SiC coating was obtained by the Chemical Vapor Deposition technique assisted by plasma. The tests were done through an ultrasonic cavitometer with a frequency of 28 kHz in an aqueous medium using tap water. According to the evidence of mass loss, results indicate that the stainless steel coated with SiC have better wear resistance than stainless steel base. In addition, failure mechanisms as cracking, plastic deformation, pits and others, were identified.
