The relation among microstructure and fatigue behavior of 2205/316L stainless steel dissimilar welded joints was investigated. Plates 6.35 mm in thickness with a single-V joint configuration were gas metal arc (GMAW) single pass by feeding at 6 m/min an ER2209 filler wire heat input 1.2 kJ/mm. Grain growth the high temperature-heat affected zone (HT-HAZ) occurred mostly mid-height plates, delim...

Diastereomeric and geometric analogs of calcipotriol, PRI-2202 and PRI-2205, were synthesized as advanced intermediates from vitamin D C-22 benzothiazoyl sulfones and side-chain aldehydes using our convergent strategy. Calcitriol, calcipotriol (PRI-2201) and tacalcitol (PRI-2191) were used as the reference compounds. Among a series of tested analogs the diastereomeric analog PRI-2202 showed the...

The enzyme UGT2B7 is one of the most active UDP-glucuronosyltransferases (UGTs) involved in drug metabolism and in maintaining homeostasis of endogenous compounds. We recently reported the existence of 22 UGT2B7 mRNAs, two with a classic 59 region but alternative 39 ends namely UGT2B7_v5 (containing a novel terminal exon 6b) and _v7 (exon 5 excluded) that encode enzymatically inactive isoforms ...

The corrosion resistance of solution annealing heat-treated type 2205 duplex stainless steel microstructures was assessed with a bipolar electrochemistry technique. Chemical element partitioning in both crystallographic phases correlated to simulations critical pitting temperatures. as-received microstructure had the highest pit nucleation resistance, high-temperature treatment revealing reduce...

The life of a concrete bridge exposed to deicing salt or seawater has often been limited by corrosion of the steel reinforcement. The service life of a concrete structure, degraded by corrosion, is considered to be the sum of the initiation and propagation periods. The initiation phase is the time required for sufficient accumulation of aggressive species at the rebar surface to initiate corros...

Electron BackScatter Diffraction (EBSD) in conjunction with Field-Emission Environmental Scanning Electron Microscopy (FEG-ESEM) has been used to evaluate the microstructural and local plastic strain evolution in different alloys (AISI 1005, AISI 304L and Duplex 2205) deformed by a single-stage cold and warm forging process. The present work is aimed to describe the different behavior of the au...
