In this paper, application of ultrasonic techniques for defect detection in weldments of austenitic stainless steel and maraging steel is discussed. Applications of ultrasonic techniques for characterizing microstructural changes in AISI type 316 stainless steel and modified 9Cr-1Mo ferritic steel; thermomechanical processing of 15Cr-15Ni-2.3Mo-titanium modified austenitic stainless steel (allo...

This paper presents an investigation of the interface quality of nanocristallised 316L stainless steel multilayer structures. They were produced by a duplex process, combining the Surface Mechanical Attrition Treatment (SMAT) and the co-rolling process at two different annealing temperatures (550°C and 650°C). Oxide layers were observed at the interfaces between the sheets and their morphology ...

the present article considers the nd:yag pulsed laser welding of 304 stainless steels with two different compositions. the effects of various laser operational parameters and cooling rates on the weld microstructures were considered. the results show that ferritic solidification is produced in the stainless steel with the creq/nieq ratio of 1.7, and austenitic solidification is produced in the ...

Microbiologically Influenced Corrosion (MIC) is a serious problem in many industries because it causes huge economic losses. Due to its excellent resistance to chemical corrosion, 2707 hyper duplex stainless steel (2707 HDSS) has been used in the marine environment. However, its resistance to MIC was not experimentally proven. In this study, the MIC behavior of 2707 HDSS caused by the marine ae...

An experimental set up consisting of an upper typodont with ivorine teeth was employed. It was fitted with the Begg brackets. Rectangular wire sectionals in 0.016"x 0.022", 0.017" x 0.025", 0.018" x 0.025" and 019" x 0.025" sizes and made of Stainless Steel, Braided Stainless Steel, Superelastic NiTi, Braided NiTi, Copper NiTi, a -Titanium and BTitanium were tested. The MAA and the four spur to...

The applications of stainless steel are one of the most reliable solutions in concrete structures to reduce chloride-induced corrosion problems and increase the structures service life, however, due to high prices of nickel, especially in many civil engineering projects, the austenitic stainless steel is replaced by the ferritic stainless steels. Compared with austenite stainless steel, the fer...

AIM The aim of this study was to compare frictional resistance which was produced between conventional brackets (0.022 slot Otho-Organiser) and self ligating brackets (active Forestadent and passive Damon III) by using various arch wire combinations (0.016 Niti, 0.018 Niti, 0.017 x 0.025 SS and 0.019 x 0.025 SS). METHODS An experimental model which consisted of 5 aligned stainless steel 0.022...

the microstructure of hp stainless steel in aged and aged + solution annealed conditions and solutionized alloy 800 was characterized by optical microscopy, scanning electron microscopy (sem), and transmission electron microscopy (tem) equipped by eds. all phases present in the above condition were described. the effects of solution annealing heat treatment temperature on the microstructure, te...
