Texture of welded joints of 316L stainless steel, multi-scale orientation analysis of a weld metal deposit

Characterization of microstructure and texture across dissimilar super duplex/austenitic stainless steel weldment joint by austenitic filler metal

“…This happened because the skeletal ferrite results from the dissolution of ferrite to austenite during cooling. This finding is in agreement with the results obtained in the literature [24][25][26][27] and confirms the cube-on-cube orientation relationship between skeletal ferrite and austenite (<001> γ ║<001> δ ) when weld solidifies preferentially in the <001> direction.…”

Creep rupture strength of activated-TIG welded 316L(N) stainless steel

“…2 and 3). The alignments were due to the maximum thermal gradient during solidification across the transverse and short transverse to the welding direction in the A-TIG and MP-TIG weld joints respectively [10]. In the A-TIG weld joint, equiaxed grains grow parallel to welding direction at the central location of weld metal ($850 lm width) which was sandwiched between columnar grains.…”

Influence of modes of metal transfer on grain structure and direction of grain growth in low nickel austenitic stainless steel weld metals

“…Understanding the grain structure and grain growth behavior of the fusion zone during welding is still evolving due to its strong influence on weld metal properties as well as development of advanced characterization tool such as electron backscattered diffraction (EBSD) technique. At present few studies are available on the EBSD analysis of welded joints of standard austenitic stainless steel (ASS), ferritic stainless steel (FSS) and duplex stainless steel (DSS) [15][16][17]. Cho et al [16] have examined the defect-free friction stir welded (FSW) joints of 409 FSS where a remarkably fine-grained microstructure in stir zone (SZ) was developed by dynamic recrystallization which eventually increased the hardness.…”

“…Even texture analysis was performed in fusion welding where plastic deformation is absent during operation. Bouche et al [15] investigated the crystallographic texture of 316L GTA weldments in fast breeder reactors on the basis of a multiscale approach and found that the ferrite dendrites ({1 0 0} δ ) were nearly parallel to the neighboring austenite columnar grains ({1 0 0} γ ) at the same fiber texture. Furthermore, Badji et al [17] have recently investigated the crystallographic texture and anisotropic properties in a 2205 DSS after gas tungsten arc welding and subsequent annealing heat treatment.…”
