in the present study, the corrosion behavior of aisi 347 austenitic stainless steel to astm a335 low alloysteel dissimilar joint was investigated. for this purpose, two filler metals, er309l and ernicr-3, were selected to be used during the gas tungsten arc welding process. to investigate the corrosion behavior of the joints after welding, the specimens were tested in 3.5% sodium chloride solut...

Metallic eye shields have been widely used for near-eye treatments to protect critical regions, but have never been incorporated into treatment plans because of the unwanted appearance of the metal artifacts on CT images. The purpose of this work was to test the use of an acrylic dummy eye shield as a substitute for a metallic eye shield during CT scans. An acrylic dummy shield of the same size...

In the present study, the Weldability and microstructure of dissimilar welds of AISI 347austenitic stainless steel to ASTM A335 low alloy steel was investigated. For this purpose, gas tungsten arc welding process and two filler metals including ERNICr-3 and ER309L were used. After welding, the microstructure of the different zones of each joint, including weld metals, heat affected zone (HAZ) 1...

Abstract: During the last decade, the demand for natural gas has steadily increased for the prevention of environmental pollution. For this reason, many liquefied natural gas (LNG) carriers have been manufactured. Since one of the most important issues in the design of LNG carriers is to guarantee structural safety, the use of low-temperature materials is increasing. Among commonly employed low...

Ternary coatings Fe-Co-W with an iron content of 40-55 at.%, cobalt 39-44 at.%, and tungsten 4-12 at.% and Fe-Co-Mo with an iron content of 40-55 at.%, cobalt 39-44 at.%, and tungsten 4-12 at.% were obtained by galvanostatic and pulse electrolysis on the mild steel substrate from iron(III) citrate-based electrolyte. The influence of electrolysis mode and parameters on composition of deposited a...

The portable germanium detector based HHRIDs are generally intended to be operated in low to medium radiation fields with as much sensitivity as possible. However, in some circumstances the interfering radioactive background may be significant with respect to the source of interest. For example: a shipping container full of NORM may be used in an attempt to mask the presence of a concealed SNM ...

The plasma-facing components (PFCs) of future fusion reactors will have intricate structures and require multiple materials because no one material can simultaneously satisfy all the requirements component. dissimilar joints in PFCs must withstand extreme thermal stress gradients under neutron irradiation. Fusion Research Oriented to Neutron Irradiation Tritium Behavior at Material Interfaces (...

12.7-mm thick plates of 6061-T6511 aluminum alloy and high hardness steel (528 HV) were successfully joined by a friction stir bonding process using a tungsten Process parameter variation experiments, which geometry, plunge and traverse rates, tool offset, spindle tilt, and rotation speed, were conducted to develop a parameter set which yielded a defect free joint. Laboratory tensile tests exhi...
