Ultrasonic 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...
متن کاملInterval Dependant Thresholding based De-noising of Ultrasonic TOFD Signals from Austenitic Stainless Steel Welds
Austenitic stainless steel has structural values in almost all industries. It is one of the most widely used materials. Qualitative assessment of such important components is of greater importance in very sensitive applications such as nuclear reactor vessels. Ultrasonic based Time of Flight diffraction is a reliable technique in testing the materials for many types of defects in welds. Echo si...
متن کاملFourier Analysis of Ultrasonic TOFD Signals for Defect Detection in Austenitic Stainless Steel Welds
Non Destructive testing of structural materials is an important activity in many industries. Ultrasonic NDT is one such method widely used in this field. Pulse Echo and Through Transmission are conventional testing techniques which use reflected and transmitted sound energy respectively. But these techniques are highly dependent on defect orientation. Time of Flight Diffraction (TOFD) is a rece...
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...
