The structural performance of microalloyed steel weld joints is essentially dependent on the microstructural characteristics of the heat-affected zone (HAZ). However, the microstructure is adversely impacted by the heat input of the welding process. As such, an X70 microalloyed steel was welded...

Welding is defined as the joining of metals with extreme heat, producing fumes, which consist of harmful metals and ultrafine particulates that may lead to detrimental health effects. Currently, air sampling is the primary method to determine welding fume exposure, but is not always feasible....

Microstructural Characterization of Chromium Carbide Overlays and a Study of Alternative Welding Processes for Industrial Wear Applications
DownloadSpring 2014
Microstructural features of chromium carbide overlays (CCOs) were examined in this work. It was found that the microstructures can contain unmelted alloy powders. It was also shown that the structures of the primary M7C3 carbides are long hexagonal rods. Change in the microstructure from the top...

Quantification of Coarse TiN-rich Precipitates in High Ti Microalloyed Steels Using EMPA Mapping and SEM/EDX
DownloadSpring 2024
Microalloyed steels are high strength steels with low alloying additions of Ti, Nb, and V. These microalloying elements form carbonitride precipitates during thermomechanical controlled processing (TMCP), which enhance the mechanical properties of steel. TiN is one of the first precipitates to...

Strain aging of microalloyed steel pipe can occur at the relatively low temperatures associated with the pipe coating process and/or during long term storage. A Box-Behnken statistical design is used to determine the significant strain aging variables that affect the longitudinal yield strength...

It is difficult to join high strength alloy steel which are produced by thermo mechanical controlled processing and get overmatched properties on the welds and heat affected zone (HAZ) when submerged arc welding (SAW) is used as joining process. Circumferential welds made in the mill to join...

Khodaie, N., Ivey, D.G., Henein, H.
Dilatometry is the most accurate and common method for measuring the kinetics of phase transformations in solid specimens. Despite the development of a more accurate technique, an inferior method, i.e., the lever rule, is widely used in the scientific community to interpret raw dilatometry data....

Ductile steel plate shear walls are an established lateral load resisting system. Past research indicates that cold-rolled infill panels less than 1 mm in thickness present one solution to an overstrength problem arising from selecting an infill panel thickness based on ease of welding and...
