Strategies for residual stress adjustment in bulk metal forming

Abstract The family of bulk forming technologies comprises processes characterised by a complex three-dimensional stress and strain state. Besides shape material properties, also residual stresses are modified during metal process. state affects important like fatigue behaviour corrosion resistance. An adjustment the is possible through subsequent process steps such as heat treatments or mechanical surface modification technologies, shot peening deep rolling. However, these additional manufacturing involve supplementary costs, longer times harmful effects on product quality. Therefore, an optimized strategy consists in targeted introduction processes. To enable this approach, fundamental understanding underlying mechanisms generation dependence parameters necessary. current art reviewed paper. Strategies for manipulation different classified according to principles modification.
