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...

P110 is a quenched and tempered (Q&T) heat-treated high strength casing used in oil/gas mild sour well drilling. Critical properties influencing performance are strength and hydrogen embrittlement (HE) resistance, which are related to carbide morphology, steel composition, and Q&T conditions....

Spring 2014
Solidification is considered as a key processing step in developing the microstructure of most metallic materials. It is, therefore, important that the solidification process can be designed and controlled in such a way so as to obtain the desirable properties in the final product. Rapid...

Valloton, J., Herlach, D.M., Henein, H., Sediako, D.
Rapid solidification of D2 tool steel is investigated experimentally using ElectroMagnetic Levitation (EML) under terrestrial and reduced gravity conditions and Impulse Atomization (IA), a drop tube type of apparatus. IA produces powders 300 to 1400 μm in size. This allows the investigation of a...

Spring 2018
Grade 91 steel is one of the most important 9-12% Cr creep strength enhanced ferritic (CSEF) steels used in fossil-fuel fired power plants. A narrow heat-affected zone with heterogeneous structures is generated in the base metal, due to non-equilibrium phase transformations during the arc welding...

Microstructure and Mechanical Characterization of Rapidly Solidified Cr-C Tool Steel - Annealing Effects
Download2016-01-01
Delshad Khatibi, P., Phillion, A.B., Henein, H.
The effect of isochronal annealing on D2 tool steel powder, rapidly solidified via both Impulse Atomization and Water Atomization, has been evaluated using high-resolution scanning electron microscopy and Vickers microhardness. The amount of supersaturation of the alloying elements inside the...

Fall 2010
The microstructures and performance of Ni-based alloys and Ni-WC (nickel-tungsten carbide) composite overlays deposited by plasma transferred arc welding have been studied. The Ni-alloy overlays had similar microstructures consisting of Ni dendrites, with interdendritic Ni-based eutectics,...
