Influence of cavitation type on damage kinetics on a low-carbon martensitic stainless steel
Abstract
This proposed study investigates the damage mechanisms and kinetics of X3CrNiMo13-4 martensitic stainless steel exposed to different types of cavitation: acoustic (MUCEF), hydrodynamic (PREVERO) and jet (CAVIJET). The studied low-carbon stainless steel is composed of a martensitic matrix with lamellar reversed austenite, residual delta ferrite, and non-metallic elements. The reversed austenite can transform to martensite when submitted to plastic deformation: this is known as the Transformation Induced Plasticity (TRIP) effect. This solid phase transformation is associated to a volumetric expansion, which produces compressive forces that allegedly delay crack initiation and propagation. Acoustic cavitation erosion tests were performed on the MUCEF equipment inspired from the ASTM G32 standards [1] using indirect method and operating at 20 kHz. Hydrodynamic erosion tests were carried out using a 40 bars cavitation flow tunnel (PREVERO) installed at LEGI laboratory at a constant cavitation number set to 0.870. Jet erosion tests were conducted using the CAVIJET device located at the Research Institute of Hydro-Québec at a pressure of 196 bars. Results show that the incubation time is the shortest for specimen exposed to CAVIJET (̴ 13min) while the longest is for PREVERO (̴ 300min) and intermediate for MUCEF (̴ 131min). Meticulous SEM observations confirmed that the damage kinetics is faster for CAVIJET and MUCEF compared to PREVERO because of the differences in bubble collapse frequency. SEM observations also show that the damage mechanisms are identical whatever the device used for conducting cavitation erosion tests. For MUCEF and PREVERO complementary XRD analysis show that, there is no correlation between the incubation time and the exposition time required for the disappearance of reversed austenite due to the TRIP effect. On the other hand, for CAVIJET the incubation time and this characteristic time are close (̴ 13min).
