Inclusion Nucleation, Growth, and Mixing during Steel Deoxidation

Nucleation and Growth of Alumina Inclusions during Steel Deoxidation

Alumina Inclusion Behavior during Steel Deoxidation

A computational model based on classic homogenous nucleation theory, thermodynamic analysis and numerical simulation, has been developed to study steel deoxidation by aluminum in a low carbon aluminum-killed steel ladle, which calculates the nucleation and time evolution of the alumina inclusion size distribution due to Ostwald ripening, Brownian collision and turbulent collision. Starting with...

Evaluation of Deoxidation Process in Medical Grade of 316L Stainless Steel

In the present work, deoxidation and refining of 316LVM steel (Low carbon Vacuum Melted) during the vacuum induction melting process was studied. This grade of stainless steel is one of the most import...

Site-Control of InAs/GaAs Quantum Dots with Indium-Assisted Deoxidation

Site-controlled epitaxial growth of InAs quantum dots on GaAs substrates patterned with periodic nanohole arrays relies on the deterministic nucleation of dots into the holes. In the ideal situation, each hole should be occupied exactly by one single dot, with no nucleation onto planar areas. However, the single-dot occupancy per hole is often made difficult by the fact that lithographically-de...

Distinguishing Anhydrate and Gypsum Scale in Mixing Incompatible Surface and Ground Waters During Water Injection Process

Determination of the type of precipitated calcium sulfate in mixing two incompatible injection and formation waters was studied experimentally in this work at two temperatures of 26oC and 80oC. Here the SEM, EDX and XRD techniques have been used to inspect the temperature effects on the morphology, type, and size of the precipitated calcium sulfate crystals. The result...
