International Journal of Computational Materials Science and Surface Engineering, 2013
This paper gives a brief overview of published results pertinent to ultrasonic shot peening, a relatively new method to introduce severe plastic deformations in the surface of materials and obtain nanosized grains. Among reported benefits are increased surface hardness and fatigue resistance, and possibility to perform nitriding at lower temperatures ...

Modelling of Ultrasonic Shot Peening
Component manufacturing may induce cold work, residual stresses, microstructure changes and even surface defects. This initial condition is usually ignored in component integrity assessments, but can strongly affect its lifetime. For instance, it is well-known that a rough surface finish associated to the presence of tensile residual stresses may favor

Impact velocity and distribution in ultrasonic shot peening
We study the dynamic of shot during an ultrasonic shot peening process from two aspects. The first consists in running various calculations of spheres placed in a cylindrical chamber (radius 35 mm, height 40 mm) and propelled by a sonotrode (frequency 20 kHz, amplitude 25 μm). This allows for a better understanding of the minimal peening time needed to

Random Approach to Peening Coverage in Ultrasonic Shot-Peening
Materials and Manufacturing Processes, 1995Abstract The so-called ultrasonic shot-peening is a new process using calibrated peening hard balls motioned by walls vibrating at 20000 Hz. As in conventional shot-peening, a fully peened surface coverage is required tor the process to be efficient. However, it is intricate to determine the coverage ratio experimentally. A statistical approach, issued

Microstructural Evolution of Super304H Upon Ultrasonic Shot Peening and Subsequent Annealing
Journal of Nanoscience and Nanotechnology, 2018In this study we analyze the effect of shot peening on the microstructure and mechanical properties of Super304H, which is widely used for boiler tubes. Specimens were shot peened for 5, 10, and 15 minutes, and then heat treated at 600, 700, and 800 °C for 15 minutes. Vickers hardness was measured and the microstructure of cross sectional specimens was
