Numerical and experimental studies on needle impact characteristics in ultrasonic shot peening
Ultrasonics, 2022Ultrasonic shot peening(USP) is an advanced surface treatment technology for obtaining excellent surface properties or manufacturing a three-dimensional curved surface of the metal sheets. The impact of the medium driven by ultrasonic vibration is significant to parameter optimization and excellent performance of the USP technology. However, the impact

Surface nanocrystallization of iron induced by ultrasonic shot peening
Nanostructured Materials, 1999A nanocrystalline surface layer was fabricated on a pure Fe plate by using an ultrasonic shot peening (USSP) technique. The USSP induced surface nanocrystallization products were characterized by means of X-ray diffraction (XRD) and transmission electron microscope (TEM).

Surface nanocrystallization of β-titanium alloy by ultrasonic shot peening
Materials Today: Proceedings, 2020Abstract A significant improvement in mechanical properties of metallic materials can be obtained through grain refinement via severe plastic deformation (SPD). The ultrasonic shot peening (USP) process is one of the SPD processes that has recently proven capability in producing ultrafine-grains at the surface of metals without affecting internal ...

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

Shot peening of selective laser-melted SS316L with ultrasonic frequency
The International Journal of Advanced Manufacturing Technology, 2021In the present work, an experimental study was carried out aiming at optimization of shot peening (SP) process with ultrasonic bombarding frequency to enhance the surface integrity of stainless steel 316 produced by selective laser melting (SLM). Here, the shots are streamed toward target surface by ultrasonic deriving unit.

Surface alloying method of ultrasonic shot peening on iron surface
Applied Surface Science, 2013Abstract A new method to generate alloying layers on the surface of iron has been developed. Ni powders are introduced to the intense plastic deformed surface of iron by ultrasonic shot peening (USP), followed by annealing at certain temperature for 30 min. Thus a surface alloy layer in a plate specimen of commercially pure iron may be produced. XRD,
