1
Copper and Copper Alloys
Thus, some type of deoxidation process is required. In addition, proper
deoxidation of all melts enhances fluidity and therefore castability. Of course,
deliberate oxidation treatments (the oxidation-deoxidation process previously
described) are ...

Secondary Steelmaking: Principles and Applications
Solution Consider deoxidation by Si (Eq. 5.37). Now, Ksi = 2.11 x 10~5 at 1600°C
(Appendix 5.1), Wsi = 0.1, and W0 = 0.01 This yields asi0^ - 0.47 . Assuming the
deoxidation product as MnO-SiO2 and using Figure 5.5, the weight percent of ...

Ferroalloys and Other Additives to Liquid Iron and Steel: A ...
Aluminum deoxidation must be carefully controlled since excessive or large
alumina inclusions can be very detrimental to casting quality. They impair
machinability and cause surface defects. Insufficient deoxidation leads to
pinholing and ...

Influence of Oxidation and
Deoxidation on Graphitization and ...
Figure 10 shows the graphite structure of the base metal, "base metal after iron
oxide addition, and the "base metal after the iron oxide addition t.nd subsequent
deoxidation with 0.2$ aluminum poured at 2500°F. Ho marked change in
graphite ...

Purification Process and Characterization of Ultra High ...
So far, theoretical aspects for oxygen removal from reactive metals using various
deoxidation techniques have been discussed. An electrochemical de- oxidation
method, which is capable of removing oxygen down to the 20 mass ppm level, ...

Extractive Metallurgy of Rare Earths
The magnitude of the limiting R value determines the possibility of sacrificial
deoxidation. If this value is more than 1 then the metal can be purified by
sacrificial deoxidation. The R values for rare earth metal-oxygen systems have
not been ...

Steel and Iron Handbook
Every attempt is therefore made to eliminate the product of deoxidation from the
melt and there by obtain clean steel. The term cleanliness refers to the relative
freedom of steel from inclusions. A gaseous product of deoxidation is, therefore, ...

Treatise on Process Metallurgy, Volume 3: Industrial Processes
Correspondingly, the interaction of other dissolved elements in steel on
deoxidation equilibria can be presented. Corresponding to Equations (1.6.9) and
(1.6.10), a general form can be written which takes into account all eventual
interactions: ...

Applied Welding Engineering: Processes, Codes, and Standards
The alternative options may include silico-managanese deoxidation and/or
vacuum carbon deoxidation. DEOXIDATION EQUILIBRIA In the previous
paragraphs of this chapter we discussed the importance, type and limitations of
deoxidation.

Extractive Metallurgy of Niobium
Deoxidation The oxygen absorption reaction in niobium is similar to that of
hydrogen and nitrogen but the mechanism of the deoxi- dation reaction(s) is very
much different as compared to that of dehydrogenation and denitrogenation
reactions.
