TL;DR: The phase transformations and mechanical behaviour during welding and subsequent annealing treatment of 2205 duplex stainless steel have been investigated in this article, where detailed microstructural examination showed the presence of higher ferrite amounts in the heat affected zone (HAZ), while higher amounts of austenite were recorded in the center region of the weld metal.

TL;DR: In this article, the effect of prior solution treatment temperature on the δ-ferrite transformation in 2205 duplex stainless welds after aging at 850°C has been studied, and the simulation of the σ-phase precipitation kinetic in the base metal, HAZ and weld metal indicates a good agreement between the experimental fitted data and the modified Johnson-Mehl-Avrami model.

TL;DR: In this article, the microstructure and the mechanical behavior of dissimilar 13Cr Supermartensitic/2205 Duplex stainless steel welded pipes were investigated and micro-tensile tests showed that the weld metal is considered as a weak link of the weld joint in the high cycle fatigue regime.

TL;DR: In this article, the plastic strain induced grain boundary migration (SIBM) is investigated by means of in-situ SEM experiments and AFM surface observations in the case of 4N pure aluminum.

TL;DR: In this paper, precipitation kinetics and the mechanical behavior in a solution treated and aged dual phase stainless steel (DSS) are investigated using X-ray diffraction, transmission and scanning electron microscopy techniques to characterize the microstructure and to identify its constituents.
