GALVANOMAGNETIC PROPERTIES OF PLASTICALLY DEFORMED InSb
n and p type InSb single crystals with as low as available initial carrier concentrations and dislocation densities were deformed by torsion or uniaxial compression. Hall effect and conductivity measurements exhibit a large decrease of the free carrier concentration and their mobilities for edge dislocations when the ratio between the carrier concentration and the dislocation density is not too...
متن کاملEffect of austenite grain size and bainite morphology on overall kinetics of bainite transformation in steels
The effect of austenite grain size on the evolution of the bainite transformation in steels is not yet certain in spite of many investigations.1–7 Barford and Owen1 reported that the reaction rate was accelerated by decreasing the grain size, because of an increase in the number density of grain boundary nucleation sites. Umemoto et al.2 reported similar results and proposed an equation that de...
متن کاملExamination of carbon partitioning into austenite during tempering of bainite
The redistribution of carbon after tempering of a novel nanocrystalline bainitic steel consisting of a mixture of supersaturated ferrite and retained austenite has been analyzed by atom probe tomography. No direct evidence supporting the additional carbon enrichment of austenite beyond that initially achieved during the bainite heat treatment was obtained during subsequent tempering of this hig...
متن کاملMagnetic Hysteresis and Barkausen Noise in Plastically Deformed Steel Sheets
The magnetic properties of steels are affected by plastic deformation, because the domain wall processes magnetoelastically interact with the dislocations and the residual stresses. The evolution of the magnetic hysteresis loop and its parameters with the type and degree of straining can thus provide a macroscopic signature of the underlying the mechanical and structural properties. Additional ...
متن کاملCombined effect of stress and strain on crystallographic orientation of bainite
The combined influence of prior plastic strain in the austenite, and applied stress in the course of the transformation, on the crystallographic texture of a bainitic steel was studied in this work. The experimental data were obtained using Electron Back Scatter Diffraction (EBSD) method and analyzed using two methodologically different approaches. It was concluded that the plastic deformation ...
