Crystallography of Widmanstätten austenite in duplex stainless steel weld metal
Two kinds of austenite grow from d-ferrite during the cooling of the duplex stainless steel weld deposits studied here, Widmanstätten plates and allotriomorphs which precipitate at d–d grain boundaries. It is found using microtexture measurements that the preferred crystallographic orientation of the Widmanstätten austenite can be estimated using established theory if it is assumed that there i...
متن کاملTemperature Dependence of Residual Stress in Tin Films on 316 Stainless Steel
The residual stresses in a TiN film deposited by a reactive ion coating process on a 316 stainless steel sheet were determined by the sin$ X-ray diffraction method, at temperatures from 15-800 “C. Using specially designed nickel clips, the coated strip was heated by the passage of a resistive current, in conjunction with a surround heater, and the temperature was measured by a Pt/Pt-lO%Rh therm...
متن کاملMeasuring of Residual Stress in TIG Welding of the 304 Stainless Steel by Ultrasonic Method
In this research, the effect of different welding parameters on residual stress and microstructure of the weld region, as well as the comparison of two methods of measuring residual stress using critical fracture longitudinal wave method and preformation method have been investigated. For this purpose, the taguchi DOE methodology is used as a statistical method to optimize four parameters of pu...
متن کاملStudy on Evaluation of Residual Phase Stress of the Dual Phase Stainless Steel
In this study , we measured residual stress in ground layer of ( CY+ r )dual phase stainless steel by X-ray diffraction. In addition, the influence of changing depth of cut on residual stress was investigated. It was found that residual stress in the a! phase was dependent on depth of cut, while the stress in Y phase was not affected by depth of cut. As a results of stress measurement under app...
