...Niraj Kumar; Chandan Pandey; Prakash Kumar In this review paper, dissimilar welding between Inconel and austenitic stainless steel along with its application has been outlined for high-temperature applications. The mechanical and microstructural behavior of this dissimilar joint has been summarized...

... behavior of weld seams is among the most stringent requirements. The microstructural characteristics and fatigue performance double-side-welded AISI 321 plate having 6 mm thickness was evaluated in this work. AISI 321 was welded with double-side-gas tungsten arc welding (DS-GTAW) process. The fatigue...

... as the proportion of base material in the weld metal, based on the predicted cross-sectional areas for the fusion zone (FZ) associated with each individual pass. The temperature predictions are consistent with the thermocouple measurement data and cross-weld macrographs. The predicted microstructures...

... in both cases have been obtained, and convection and radiation coefficients of flux-covered X80 pipeline steel in air-cooled environment have been corrected. By using sysweld software, a finite-element computational model was set up for microstructure and residual stress in the weld zone of multiwire...

... on the rules of influence of a post weld medium-frequency heat treatment process on microstructural change and the rules of residual stress distribution, and proposes a quantitative analysis method for studies on heating mechanisms of on-line heat treatment. The microstructural evolution process respect...

... Figure 13 shows the HAZ microstructure of laser zone and arc zone. It could be clearly found that two zones are composed of coarse grain zone adjacent to fusion zone, fine grain zone and incomplete recrystallization zone adjacent to base metal. Figure 14 is higher magnification micrographs...

...Andrey P. Jivkov; Nicholas P. C. Stevens; Thomas J. Marrow The resistance of polycrystalline materials to intergranular cracking can be influenced by the microstructure. In sensitized stainless steels, for example, the grain boundaries prone to sensitization form paths of low resistance...

..., and a comparison is made with stress measurement obtained by incremental hole-drilling method, and X-ray diffraction. These results are also validated by thermal relaxation of the plates. The paper discusses also the microstructure influence on ultrasonic measurements and methods for adjusting the ultrasonic...
