Stability of forming induced residual stresses in stainless steel parts at elevated temperature
Andreas Jobst
Abstract:The performance characteristics of technical components are influenced by residual stresses. Depending on their sign and magnitude, they may decrease or enhance the products’ fatigue strength, corrosion resistance and its achievable lifetime. While compressive stresses in the part surface usually increase the fatigue strength, tensile stresses promote crack initiation and growth. In many cases, the forming induced residual stress state is either unknown or tensile, which is why stress-relief annealing is perfo… Show more
