Effects of shot peening pressure, media type and double shot peening on the microstructure, mechanical and tribological properties of low-alloy steel

Surface Topography: Metrology and Properties, 2016
The effects of different shot peening conditions such as pressure (from 68.9–551.6 kPa), media type (media S230 and S110) and double shot peening on the microstructure, mechanical and tribological properties of shot peened AISI 4340 low-alloy steels, were systematically investigated.

Residual Stress Asymmetry in Thin Sheets of Double-Sided Shot Peened Aluminum

Journal of Materials Engineering and Performance, 2019
The local mechanical properties and residual stresses of a double-sided shot-peened aluminum alloy AA7050-T7451 sheet were measured by nanoindentation and simulated by the finite element method (FEM). The variation of the pileup area around the indentation due to residual stresses, as well as changes in hardness as a function of cold working, was ...

Improvement of spring fatigue strength by new warm stress double shot peening process

Materials Science and Technology, 2002
Abstract Shot peening technology plays a very important role in improving the fatigue strength of springs. In the present paper a new warm stress double shot peening (WSDSP) process developed by the authors is described. The authors have previously proposed a warm stress shot peening (WSSP) process, which is a combination of warm shot peening (WSP) and

Effect of Double Shot Peening on Room-Temperature Notched Fatigue Property of TC4 Titanium Alloy

Materials Science Forum, 2015
Single shot peening (SSP) with cast-iron shot and double shot peening (DSP) with cast-iron shot and ceramic shot were applied to investigate the relationship between surface integrity status and the fatigue property of titanium alloy TC4 on the notched specimens (stress concentration coefficient Kt=1.7).

Effect of shot peening pretreatment on the high-temperature tribological behaviours of a TaN coating prepared via double-cathode glow plasma alloying

Surface and Coatings Technology, 2021
Abstract Gradient coatings with excellent physical and mechanical properties show great potential for use in engineering applications. In this study, a TaN gradient-modified layer was prepared on TA15 titanium alloy by double-cathode glow plasma alloying (DGPA) with a gradient structure pretreated by rotationally accelerated shot peening (RASP).
