Journal of Materials Research and Technology, 2021 Soft zone formation in dissimilar Cr–Mo welding occurs during post weld heat treatment that could compromise the integrity of the weldment. The decomposition of martensite could cause this formation at the weld heat affected zone adjacent to the fusion boundary. There could not yet determine the actual width of this zone.

Characterisation and understanding of the corrosion behaviour of the nugget in a 2050 aluminium alloy Friction Stir Welding joint [PDF]
, 2013 The corrosion behaviour of the nugget of a Friction Stir Welding joint employing a 2050 Al–Cu–Li alloy was investigated. The results showed that the nugget was susceptible to both intergranular and intragranular corrosion.

Measurement of residual stresses induced by sequential weld buttering and cladding operations involving a 2.25Cr-1Mo substrate material [PDF]
, 2017 Dissimilar metal welds are necessary in high-pressure subsea systems and in cases where forged components must be welded to pipelines. F22 (2.25Cr-1Mo) steel is often used in such forged steel components and, since this steel cannot enter service without

Residual stresses in condition monitoring and repair of thermal power generation components [PDF]
, 2017 Residual stresses have a significant impact on fatigue and fracture of engineering components and structures, with an effect that is largely dependent on the sign of the residual stress relative to that of the applied stress, i.e. on whether they add to,

Evidence-Based Complementary and Alternative Medicine, Volume 2020, Issue 1, 2020., 2020 Purpose. Retinal ischemia is a medical condition associated with numerous retinal vascular disorders, such as age‐related macular degeneration, glaucoma, and diabetic retinopathy. This in vitro cell and in vivo animal study investigated not only the protective effect of S‐allyl L‐cysteine (SAC, an active component of garlic) against retinal ischemia ...

Advances in Materials Science and Engineering, Volume 2020, Issue 1, 2020., 2020 In this study, the integrity of electron beam‐ (EB‐) welded CA6NM—a grade of 13% Cr‐4% Ni martensitic stainless steel—was assessed through the entire joint thickness of 90 mm after postweld heat treatment (PWHT). The joints were characterized by examining the microstructure, residual stresses, global mechanical properties (static tensile, Charpy impact,
