The Strain Dependence of Post-Deformation Softening during the Hot Deformation of 304H Stainless Steel
Experiments were carried out in which the dependence of the fractional softening on temperature, time and strain rate was determined in a 304H stainless steel. Three prestrain ranges were identified pertaining to three different post-deformation softening behaviors: 1) prestraining to below the DRX critical strain: strongly strain dependent softening by SRX alone with softening kinetics control...

This paper (SPE 173892) was revised for publication from paper OTC 25335, first presented at the Offshore Technology Conference, Houston, 5–8 May 2014. Original manuscript received for review 20 June 2014. Revised manuscript received for review 27 October 2014. Paper peer approved 4 November 2014. Summary Steel catenary risers (SCRs) on a large-heave-motion vessel are susceptible to compression...
متن کاملFinite Element Modeling of Deformation Behavior of Steel Specimens under Various Loading Scenarios
Lightweighting materials (e.g., advanced high strength steels, aluminum alloys etc.) are increasingly being used by automotive companies as sheet metal components. However, accurate material models are needed for wider adoption. These constitutive material data are often developed by applying biaxial strain paths with cross-shaped (cruciform) specimens. Optimizing the design of specimens is a m...
متن کاملPredicting the buckling Capacity of Steel Cylindrical Shells with Rectangular Stringers under Axial Loading by using Artificial Neural Networks
A parametric study was carried out in order to investigate the buckling capacity of the vertically stiffened cylindrical shells. To this end ANSYS software was used. Cylindrical steel shells with different yield stresses, diameter-to-thickness ratios (D/t) and number of stiffeners were modeled and their buckling capacities were calculated by displacement control nonlinear static analysis. Radi...
متن کاملDynamic Recrystallization under Hot Deformation of a PH Stainless Steel
Dynamic recrystallization, DRX, behaviour of a precipitation hardened, PH, stainless steel was studied in connection with microstructural developments in a compression test. The experimental results showed that the dominant mechanism of softening is DRX, but at high strain rates and low temperatures, ie, high Zener-Holman parameter, Z, work hardening and dynamic recovery, DRV, produced a pancke...
