Behavior of Alumina Inclusions Just after 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...

Deoxidation of Graphene using Caffeic Acid

The graphene which is a two dimensional carbon structure has been significantly explored due to its excellent mechanical and physical properties. Based on its prominent properties, graphene has a wide range of useful applications. Among the methods for synthesizing graphene, chemical method is known as the most powerful method for mass production of graphene. During the process, to achieve high...

The Effect of Inclusions on Through-thickness Directional Fatigue Behavior of S355N Steel Plate

Microalloyed S355N steel plates are extensively used in bridge and high-rise building structures. One of the factors affecting the mechanical properties is the size and morphology of inclusions. In this research, microalloyed S355N steel plates with different sizes of inclusions were examined. One contained long manganese sulfide inclusions (LI material) and the other had short ones (SI materia...

Copper Deoxidation Kinetics Utilizing Carbon Monoxide

Gaseous deoxidat ion of l iquid copper with carbon monoxide as the r educ ing gas has been examined . The r educ ing gas was in t roduced at a s u b m e r g e d or i f ice so that well c h a r a c te r ized , s ingle bubbles were formed.
