The resistance of S235JR steel to cavitation erosion
Wear, 2020Abstract The erosion resistance of S235JR steel to flow cavitation was investigated. In order to understand an influence of steel properties and cavitation intensities on the degradation mechanisms, low-carbon S235JR steel was tested in the as-received state and after thermal treatment (annealing) under four different flow velocities.

Wear behavior of ultrasonic impact treated S235JR steel
Materialpruefung/Materials Testing, 2017Abstract In this study, wear behavior of ultrasonic impact treated S235JR steel was investigated. Samples were peened for different times (5, 15 and 30 minutes) by ultrasonic impact treatment. It was found that triple layers (nanocrystallization, plastic deformation and residual stress) formed on the treated surface. The thickness of the

Microstructural failure criteria for S235JR steel subjected to spatial stress states
Archives of Civil and Mechanical Engineering, 2015Abstract The study deals with failure criteria for S235JR steel subjected to spatial stress states. The predictions were made using the modified Gurson–Tvergaard–Needleman (GTN) material model, which takes into account the effect of microstructural damage.

This paper analyzes the changes in the state of stress in the plastically deforming structural steel which are attributable to the evolution of defects in the microstructure of the material. Numerical simulations were conducted to study the behaviour of a structural element under tensile stress using the Gurson-Tvergaard-Needleman material model for ...

Materials Science and Welding Technologies
The article presents the results of physical experiments consisting in the rolling of layered plates (clad plates). The experiments involved two types of two-layered flat bars, i.e. S235JR and X20Cr13 as well as S235JR and X5CrNi18-10. The experiment resulted in the development of a technology for the fabrication of layered flat bars made of structural
