“…Hence, to achieve the benefits of corrosion resistance in the DSS weld, the welding parameters such as heat input, interpass temperature, shielding gas with appropriate nitrogen content, and types of welding processes have to be utilized properly within the permissible limits. Recent study reveals that the use of electromagnetic interaction with low intensity during welding is an alternative way to improve the corrosion resistance of DSS weldments by avoiding the formation of deleterious phases such as sigma, carbides, and nitrides [84] .…”

“…It has been shown that the high alloying content in these steels increases the risk of precipitation of intermetallic phases, with a negative effect on the corrosion resistance and ductility [5][6][7]. For example, it was reported that precipitation of sigma phase determines the formation of Cr-depleted determines the formation of Cr-depleted zones [12,13], leading to a decrease of mechanical and corrosion resistance and finally to premature failure [14][15][16][17][18][19][20]. The microstructural evolution of SDSS after hot deformation and subsequent solution annealing is very important for preventing the formation of deleterious intermetallic phases and, therefore, the easiest solution to achieve the desired properties seems to be a proper control of thermo-mechanical treatment [21][22][23][24][25].…”

Abstract:In this present study, the influence of solution annealing temperature on microstructural properties of a forged Super Duplex Stainless Steel (SDSS) was investigated by SEM-BSE (Scanning Electron Microscopy-Backscattered Electrons) and SEM-EBSD (Scanning Electron Microscopy-Electron Backscatter Diffraction) techniques. A brief solution treatment was applied to the forged super duplex alloy, at different temperatures between 800 • C and 1100 • C, with a constant holding time of 0.6 ks (10 min). Microstructural characteristics such as nature, weight fraction, distribution and morphology of constituent phases, average grain-size and grain misorientation were analysed in relation to the solution annealing temperature. Experimental results have shown that the constituent phases in the SDSS alloy are δ-Fe, γ-Fe and σ (Cr-Fe) and that their properties are influenced by the solution treatment temperature. SEM examinations revealed microstructural modifications induced by the Cr rich precipitates along the δ/γ and δ/δ grain boundaries, which may significantly affect the toughness and the corrosion resistance of the alloy. Solution annealing at 1100 • C led to complete dissolution of σ (Cr-Fe) phase, the microstructure being formed of primary δ-Fe and γ-Fe. The orientation relationship between δ/δ, γ/γ and δ/γ grains was determined by electron back scattering diffraction (EBSD). Both primary constituent phase's microhardness and global microhardness were determined.

“…The toughness and hardness in the molten zone increased with increased formation of γ-phase. García-Rentería et al [ 7 ] studied the resistance to localized corrosion of AISI 2205 steel joined by MAG welding under the effect of electromagnetic interaction. Results show the modified microstructural evolution of welded joints induced by application of electromagnetic interaction during welding is associated with the increase of resistance to localized corrosion of the welded joints.…”

Stress relief treatments were carried out separately with a pneumatic chipping hammer, ultrasonic peening treatment, and heat treatment for metal active-gas welding (MAG) welded joints of 2205 duplex stainless steel. The effects of these methods on the residual stress, microstructure, mechanical properties and corrosion resistance of welded joints were studied. Results show the stress state of the weld and the surrounding area was effectively improved by the pneumatic chipping hammer and ultrasonic peening treatment, and the residual stress field of the surface layer changed from tensile stress to compressive stress. On the contrary, low-temperature stress relieving annealing had no obvious effect on stress distribution. After the pneumatic chipping hammer and ultrasonic peening treatment, the welded joints were machined and hardened. Correspondingly, strength and hardness were improved. However, the heat treatment only led to a slight decrease in strength and hardness due to the static recovery of the welded joint structure. All stress relief methods effectively improved the corrosion resistance of welded joints, with the ultrasonic peening treatment giving the best performance.
