Effect of repeated weld-repairs on microstructure, texture, impact properties and corrosion properties of AISI 304L stainless steel

Relationships between microstructures and properties of buffer layer with Inconel 52M clad on AISI 316L stainless steel by GTAW processing

“…A reduction in the temperature of the specimen would cause the elements to begin solidifying into their preferred crystalline structure. During the dilution process (as the welding pool solidifies), the atoms belonging to the various elements interfere with one another, resulting in diffusion [27,28]. In a molten state, the elements are not in equilibrium and the concentration and flux of the solutes cannot be predicted.…”

Effects of Heat Input on Microstructure, Corrosion and Mechanical Characteristics of Welded Austenitic and Duplex Stainless Steels: A Review

“…Nitride precipitation was noted in HAZ. The presence of δ-ferrite with higher Cr content may deleteriously affect the corrosion resistance because of the potential difference between the δ-ferrite and austenite phases [109], but this The weld metal of DSS is more resistant to pitting corrosion than the base metal. Furthermore, the enhanced response of weld metal to pitting resistance is associated with the addition of Cr and Ni elements [105].…”

“…Nitride precipitation was noted in HAZ. The presence of δ-ferrite with higher Cr content may deleteriously affect the corrosion resistance because of the potential difference between the δ-ferrite and austenite phases [109], but this factor may exert less influence on the corrosion resistance than the others. The corrosion properties of the welds also include grain boundary effects [110,111].…”

Recent durability studies on concrete structure

“…Besides, the bond properties between the concrete and the epoxy-coated rebar are not as strong as between concrete and conventional rebar, which should be improved [2]. 3) There have been a few investigations on the use of stainless steel bars [68][69][70][71][72]. It has been shown that the chloride threshold value for initiation of corrosion in non-welded AISI 304 (a kind of stainless steel) rebar is three to five times higher than that of conventional rebar.…”
