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...

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. The deoxidat ion k ine t ics a r e d e t e r m i n e d p r i m a r i l y by the m a s s t r a n s p o r t of oxygen in l iquid copper. No effect of su l fur ov...

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...

Deoxidation of fenthion sulfoxide, fenthion oxon sulfoxide and fensulfothion in gas chromatograph/mass spectrometer, and the prevention of sulfoxide deoxidation by polyethylene glycol 300.

Fenthion, fenthion sulfoxide, fenthion oxon sulfoxide and fensulfothion showed two different mass spectra in GC/MS, depending on their concentrations. The base peaks shifted to lower levels by 1 m/z at lower concentration, and no retention time shifts were observed. The "shifted base peaks" were not obtained by a general EI fragmentation. The product ion scan spectra of the "shifted base pea...
