“…A small amount of -ferrite is required to avoid hot cracking during weld solidification (Patchett & Bringas, 2003). Some studies (Fang et al, 1994;Prasad et al, 2014;Shaikh et al, 1993) confirmed the occurrence of selective dissolution in δ-ferrite, which resulted in corrosion-related failure of welded austenitic stainless steels. The HAZ is attacked by microstructural changes caused by heating and cooling cycles.…”

“…Despite their excellent resistance to general ASSs are susceptible to stress corrosion cracking (SCC). However, welding, which is distinguished by rapid heating and cooling, exacerbates SCC in ASS due to microstructural evolution and metallurgical changes (Prasad et al, 2014).…”

“…% (ASM International, 2008). These alloys are widely utilized in several engineering applications, particularly in the pressure vessels, chemical, food, transportation, and medical industries, due to a combination of corrosion resistance, minimal maintenance, low cost, and excellent mechanical properties (Prasad et al, 2014;Warikh Abd Rashid et al, 2012).…”

The formation of a protective chromium carbide passive film makes austenitic stainless steel (ASS) alloys suitable for corrosive and high-temperature environments. This paper examined the transformation of the microstructure, corrosion, and mechanical properties of gas tungsten arc welded 316 austenitic stainless steel. The scientific principles governing metallurgical transformation and corrosion dynamics were discussed. The review shows that passive film on 316L ASS gradually erodes as the concentration of chloride ion rises. Metallurgical properties of FZ are completely changed, and solid-state transformation occurs at HAZ during the GTA welding process. These transformations affect the microstructure, corrosion, and mechanical properties of GTA welded ASS alloys.

“…5 Furthermore, employing low-carbon steel (AISI 316L stainless steel) minimizes crack susceptibility. 6,7 These steels have high chromium and nickel content, which makes them more corrosion resistant at high temperatures. Despite their great corrosion resistance, austenitic stainless steels are vulnerable to pitting corrosion and stress corrosion cracking in extremely corrosive environments.…”

The present work discusses the macrostructure, microstructure, and microhardness of dissimilar metal weld joints between AISI 316L SS-DSS 2205 developed by gas tungsten arc welding (GTAW) welding. Post-weld heat treatments (PWHT) were carried out at temperatures of 750°C for 24 h and 850°C for 0.5 h. The macrostructure and microstructure of the welding joints at different welding conditions were observed by scanning electron microscope. The macrostructure study results indicated that all the welded joints were fully penetrated and free from defects. However, the microstructure investigation revealed a solid-state transformation of ferrite into grain boundary austenite, widmanstatten austenite, intergranular austenite, and partially transformed austenite. The post-weld heat treatment processes enhanced the precipitation of the sigma phase in the ferrite matrix. Secondly, the microhardness across and along the weld bead has been evaluated, and the results are compared. It was observed that the microhardness of the heat-affected zone of DSS 2205 is found to be higher as compared to a heat-affected zone of AISI 316L, the weld metal zone, and base metals at all welding currents (i.e. 90 A, 109 A, and 132 A). The microhardness values decrease when transverse from the face of the weld toward the root pass. Microhardness values at the fill (top) pass of the weld zone at 90 A, 109 A, and 132 A were 268.3 HV, 257 HV, and 255 HV respectively. It was found that the microhardness has improved significantly after post-weld heat treatments and was highest for 750°C/24 h. It may be due to higher holding time which led to the involvement of carbides.

“…Our study will be focused on stainless steel AISI 304-carbon steel ASTM A105 joints. The AISI 304 grade stainless steel has good mechanical properties and high corrosion resistance [19], ASTM A105 carbon steel has attractive properties such as high strength, good wear resistance, and affordable cost. In many applications, dissimilar welded joints play a key structural role and they are often subjected to cyclic stresses.…”

Our study will be focused on stainless steel AISI 304—carbon steel ASTM A105 joints obtained by rotary friction welding and on their fatigue corrosion behavior in different testing environments. As a first thing, the joints will be characterized by microscopy and electrochemical techniques. The manuscript will then describe the optimization of the experimental setup and the validation of the testing procedure. After that, the fatigue behavior of the joints will be tested in different aggressive environments. This study pointed out that it is possible to build a simple and low-cost setup for the study of fatigue corrosion behavior of dissimilar joints while exploiting in situ electrochemical measurements to follow the fatigue corrosion process.
