Optimum Application of Ultrasonic Peening
نویسنده
چکیده
A new advanced system for Ultrasonic Peening (UP) of materials, details and welded elements was developed recently. The UP produces a number of beneficial effects in metals and alloys. Foremost among these is increasing the resistance of materials to surface-related failures, such as fatigue, fretting fatigue and stress corrosion cracking. The beneficial effect is achieved mainly by relieving of harmful tensile residual stresses and introducing compressive residual stresses into surface layers of metals and alloys, decrease in stress concentration of weld toe zones and the enhancement of the mechanical properties of the surface layer of the material. The results of experimental studies and computation of the effect of UP on the fatigue life of welded elements are presented in this paper. A new advanced equipment and software for UP optimum application are introduced.

Ultrasonic shot peening (USP) studied. Several parameters (arc heights, surface roughness topography and micro hardness) with different parameters were measured. The research proposes curvature of shot peened sheet increases with time decreasing, while increases with pin diameter increasing, and curvature reaches a saturation level after a specific electric current. An empirical model of the re...
متن کاملThe Effect of Ultrasonic Peening Treatment on Fatigue Performance of Welded Joints
Ultrasonic peening treatment (UPT) as a method of severe plastic deformation was used to treat cruciform welded joints of Q345 steel. The application of UPT achieves material surface nanocrystallization of the peening zone, reduces stress concentration, and produces residual compressive stresses at the welded toe. Micro-structure, hardness, stress relief, S-N curve, and the fatigue fracture mec...
