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).

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

Flexible Sheet Forming Technology by Double-sided Simultaneous Shot Peen Forming

CIRP Annals, 2002
Abstract The exceptionally flexible forming technology shot peen forming is used primarily on large, three-dimensionally curved sheet metal in the aircraft and aerospace industries. Depending on the kinetic shot energy, both convex and concave curvatures will be generated.

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 ...

Relation of Compression Residual Stress on Pre-Tensioned Surface in Parabolic Leaf Spring Submitted to the Stress Shot Peening Process in Carbon Steel

SAE technical paper series, 2023
This work deals with the effect of different blasting conditions under stress on the intensity and distribution of compressive residual stresses. The tests were performed on bars measuring 17 mm x 70 mm x 1700 mm in AISI 51CrV4 carbon steel.

Effects of processing parameters on residual stress fields of 2024-T351 alloy blade subjected to massive double-sided laser peening treatment

Journal of laser applications, 2022
Double-sided laser shot peening (DSLSP) is a promising technique for improving mechanical properties for thin-section components. Residual stress (RS) field induced in the thin 2024-T351 alloy blade by DSLSP was investigated through experiments and ...
