Fatigue properties of welded Strenx 700 MC HSLA steel after ultrasonic impact treatment application

Popis výsledku v původním jazyce

Ultrasonic impact treatment is a recent post weld treatment technique which can be applied to straighten the welding deformations and to increase the fatigue endurance due to the positive effect of deformation strengthening of surface layers, induction of compressive residual stresses in the sub-surface layers and decreasing the surface roughness. Ultrasonic impact treatment was applied on welded joints manufactured from Strenx 700 MC high strength low alloy steel with the aim to improve its fatigue endurance. Three different parameters of ultrasonic impact treatment were applied and their influence on the fatigue endurance was studied. Based on measurements of residual stresses in the surface and sub-surface layers, surface roughness and results of fatigue tests the optimal parameters of ultrasonic impact treatment process were determined. As a result, it was possible to increase the fatigue limit at N = 107 cycles by about 12%.
