Shot peening is a mechanical surface treatment to improve the fatigue strength of metallic components. Similarities exist between regular shot peening and conventional industrial clean blasting. However, the main difference between these two processe

The induction of near-surface compressive residual stress is an important factor for fatigue life improvement of HFMI-treated welded joints. However, the relaxation of these beneficial residual stresses under single overload peaks under variable ampl

One of the main problems in the machining of thin-walled parts made of high-strength aluminum alloys is distortion and dimensional instability after machining, which leads to an increase in scraped parts and the cost of production. In general, distor

The micromagnetic measurement method is a fast and easy to handle alternative for the determination of residual stresses in steel welds. The accuracy is lower in comparison to diffraction techniques but it can be applied faster and under rough condit

Investigations have been carried out regarding the fatigue strength of welded details improved by high frequency treatment methods. These methods increase the fatigue strength by cold forming of the surface, so that the weld toe is smoothened, the su

Zur Charakterisierung der ermudungsrelevanten Werkstoffveranderungen infolge hochfrequenter Schweisnahtnachbehandlung hat sich der Einsatz von mikromagnetischen Werkstoff- und Spannungsanalysen vorteilhaft gezeigt. Fur Standardbauteile hat sich gezei

Investigations on welded joints of a low strength steel and of an age-hardened aluminium- alloy have been performed to compare the effects of different post-weld treatment methods. The experimental results show, that the methods which are working wit
