Bending Fatigue Failures in Valve Steel
In the present paper the effect of defects (viz. pits, gouges and oxide inclusions) will be reported. Although certain defects were uniformly distributed over the specimen surface, the majority of all fractures started in the edge region. An explanation to this behaviour is presented in terms of stress enhancement in the edge regions due to edge deflections.
متن کاملHydrogen Assisted Cracking in Pearlitic Steel Rods: The Role of Residual Stresses Generated by Fatigue Precracking
Stress corrosion cracking (SCC) of metals is an issue of major concern in engineering since this phenomenon causes many catastrophic failures of structural components in aggressive environments. SCC is even more harmful under cathodic conditions promoting the phenomenon known as hydrogen assisted cracking (HAC), hydrogen assisted fracture (HAF) or hydrogen embrittlement (HE). A common way to as...
متن کاملRotary-bending fatigue characteristics of medical-grade Nitinol wire.
The rotary bending fatigue properties of medical-grade Nitinol wires were investigated under conditions of 0.5-10% strain amplitudes to a maximum of 10(7) cycles. The results from this study provide insight into the behavior of Nitinol under fully reversed (εmin/εmax=-1) fatigue conditions for three compositions, two surface conditions and three test temperatures. For pseudoelastic conditions t...
متن کاملThe Effect of Multiple Bending of Wire on the Residual Stresses of High Carbon Steel Wires
R. Kruzel, M. Suliga, Czestochowa University of Technology, Czestochowa, Poland Steel tire cord, springs and rope wires belong to the group of metal products from which the low residual stresses are required. In this paper the eff ect of multiple bending of wire on residual stresses of high carbon steel wires has been assessed. It was found that the application of the multi-roller straightening...
