Microstructural Evolution of Super304H Upon Ultrasonic Shot Peening and Subsequent Annealing

Journal of Nanoscience and Nanotechnology, 2018
In 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

CAD based model of ultrasonic shot peening for complex industrial parts

Advances in Engineering Software, 2014
This paper presents a numerical model developed specifically for ultrasonic shot peening (USP). It allows simulating the shot dynamics (trajectories in the chamber and impacts on the peened sample) in industrial configurations. The model supports complex 3D geometries, rotating parts and employs efficient collision detection algorithms for short ...

Shot peening of selective laser-melted SS316L with ultrasonic frequency

The International Journal of Advanced Manufacturing Technology, 2021
In 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, 2013
Abstract 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,

Impact velocity and distribution in ultrasonic shot peening

2011
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
