... stress has also been reported for different metals and alloys [ 36 , 37 ]. An average value of rate constant ε c  = 0.03 was obtained for range of stresses examined in the present investigation. The variations in tertiary creep constants β and η with applied stress are shown in Fig. 10 . The value...

Results showed that thin plates accumulate the heat, which cause grain coarsening and loss of acicular ferrite (AF) microstructure, which is further responsible for lower impact strength...

... effects at low Δ K . The FCGR at low Δ K decreases since the driving force decreases; however, the metal dissolution rate at the crack tip is largely uninfluenced by the Δ K but is primarily a time-dependent phenomenon. Hence, as the FCGR decreases, the metal dissolution at the crack tip can play...

...D. Rudland; A. Csontos; T. Zhang; G. Wilkowski At the end of 2006, defects were identified using ultrasonic testing in three of the pressurizer nozzle dissimilar metal (DM) welds at the Wolf Creek nuclear power plant. Understanding welding residual stress is important in the evaluation of why...

...Xian-Kui Zhu; Brian N. Leis To accurately characterize plastic yield behavior of metals in multiaxial stress states, a new yield theory, i.e., the average shear stress yield (ASSY) theory, is proposed in reference to the classical Tresca and von Mises yield theories for isotropic hardening...
