“…Shear bond strength of two specimens at least was tested for each condition, and the average value was calculated. The detailed dimensions of the shear test specimens were illustrated in [24,25], which ensured the fracture along with the bonding interface. For observing microstructure after experiments, the specimens were cut per-pendicular to the bonding interface along the rolling direction.…”

Aiming at the requirement of lightweight and corrosion resistance, superplastic diffusion bonding of 2205 duplex stainless steel was studied. The results showed that during the pretreatment procedure, with the increase of pre-solution temperature from 1050 to 1350 • C, cold roll reduction from 50 to 85 %, the joint shear strength was improved after bonded under the same condition. The pretreatment of solution at 1350 • C and cold rolled by 85 % was a better choice for the diffusion bonding of 2205 duplex stainless steel. During the bonding process, the critical value of holding time, holding pressure, and bonding temperature were determined as 5 min, 10 MPa, and 1000 • C, before which the joint shear strength was fast increased and after which it was slowly increased or even decreased. Due to the σ-phase dispersed along with the interface after bonded, post-solution treatment was considered, and after post-solution at 1050 • C for 10 min, the best joint shear strength of 685 MPa was obtained.

“…The potential use of MMCs includes not only applications at high and steady temperatures (isothermal conditions) but also uses in which changing temperature (thermal cycling) conditions, such as in some engine parts, can be relevant [8]. Although their good isothermal creep behavior has been demonstrated [2,3], it is important to note that when the experimental conditions involve severe temperature changes, the tensile behavior of MMCs undergoes dramatic changes, as it has been shown in several investigations [8][9][10][11][12][13]. In summary, these materials deform under very low applied stresses, but at relatively high strain rates, in comparison to deformation behavior under isothermal creep conditions.…”

“…Previous studies show that the fraction of ferrite will be decreased while the fraction of austenite will be increased after hot working [7][8][9][10][11]. Thus austenite becomes the matrix during hot deformation of DSS, and it plays a decisive role in the hot deformation process.…”

Due to attractive strength, toughness, and corrosion resistance, duplex stainless steels (DSS) are widely used in various applications. The current study performs a systematic investigation on the microstructure and orientation of austenite in DSS during superplastic deformation. Results show that austenite grains became uniform, equiaxed, coarse, and some were elongated. The superplastic deformation could weaken textures in Gauss {011}<100>, Brass {011}<211> and Copper {211}<111> orientations. Dynamic recovery followed by continuous dynamic recrystallization occurred in austenite during superplastic deformation. Concentrated strain in softer ferrite phase leads to a slightly lower dislocation density in austenite. This paper provides new insight into the deformation mechanism of the austenite matrix during hot deformation in duplex stainless steels.
