Lattice strain evolution during uniaxial tensile loading of stainless steel
Applied and residual lattice strains were determined by neutron diffraction during a tensile test of a weakly textured austenitic stainless steel and were compared to the predictions of a self-consistent polycrystal deformation model. Parallel to the tensile axis the model predictions are generally within the resolution of the diffraction measurements, but perpendicular to the tensile axis disc...
متن کاملHot tensile properties and strain hardening behaviour of Super 304HCu stainless steel
Super 304HCu austenitic stainless steel containing 2.3–3 (wt.%) of Cu is mainly used in superheaters and reheaters tubing of ultra super critical boilers which operates over 600 ◦C of steam temperature. Tensile tests were carried out on Super 304HCu, using nominal strain rate of 1 × 10−3 s−1, at room temperature, 550 ◦C, 600 ◦C and 650 ◦C. The tensile strength and elongation were found to decre...
متن کاملMicrostructure Evolution during Tensile Deformation of a Nanostructured Bainitic Steel
In situ neutron diffraction experiment was used during tensile testing at room temperature to examine the changes on the percentage and texture of both ferrite and austenite in a nanocrystalline bainitic steels transformed at two different temperatures 200°C and 300oC for different times to achieve the same phase percentages. Both samples showed an inadequate capability of austenite to transfor...
متن کاملCrystallographic texture evolution in 1008 steel sheet during multi-axial tensile strain paths
This paper considers the crystallographic texture evolution in a 1008 low carbon steel. The texture evolution along uniaxial, plane strain and balanced biaxial strain states were measured. For uniaxial testing, grains tend to rotate such that the {111}〈11̄0〉 slip directions are aligned with the loading axis. For plane strain and balanced biaxial strain states, the majority of grains are distribu...
متن کاملThe 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...
