Formation of annealing twins during recrystallization and grain growth in 304L austenitic stainless steel
Understanding of the mechanisms of annealing twin formation is fundamental for grain boundary engineering. In this work, the formation of annealing twins in a 304L austenitic stainless steel is examined in relation to the thermo-mechanical history. The behavior of annealing twins of various morphologies is analyzed using an in-situ annealing device and EBSD. The results confirm that there is a ...
متن کاملCorrosion Behaviour of Nickel Coated AISI 316 Stainless Steel as a Function of Annealing Temperature
AISI 316 stainless steels were coated with 250 nm Ni film by electron beam deposition and post-annealed at different temperatures with a nitrogen flow of 600 cm3min-1 nitrogen. The prepared samples were corrosion tested in 1.0 M sulphuric acid solution using potentiodynamic technique. Crystallographic and morphological structure of the samples were analyzedanalysed by X-ray diffraction (XRD) an...
متن کاملSensitization Behavior of Gnaw Austenitic Stainless Steel Joints
The present work has been carried out to study the sensitization behavior of AISI 304L austenitic stainless steel weld, fabricated using GTAW (gas tungsten arc welding process). This weld was subjected to post weld thermal aging (PWTA) treatments lying in the sensitization range, viz. 700 ?C for 30 minutes, 500 minutes and 1000 minutes for studying the influence of carbide precipitation on thei...
متن کاملExperimental Quantification of Phase Transformation in Austenitic Stainless Steel
This conference paper briefly discusses different techniques for measuring the evolution of the martensite content in cold-rolled stainless steel 301LN sheets under mechanical loading. Three methods are employed to measure the martensite content: (1) micrography, (2) bulk magnetic induction, and (3) local magnetic permeability measurements. The first two methods require the extraction of sample...
متن کاملUltrasonic Characterization of Austenitic Stainless Steel in Thermal Variations
This work focuses on the ultrasonic characterization and hardness of Austenitic stainless steel in thermal variation. The sample which was heat treated at 1050 o C has the highest hardness value and plays a dominant role in dispersion of carbides. Shear wave velocity and hardness show similar trend in variation with temperature. The effect of volume expansion would be to decrease the elastic co...
