Figures 2-5 show the evolution of filiform corrosion from the scribe on the matrix at 250, 500, 750, and 1000 hr for alkaline-cleaned, chromate-based deoxidation, CeCC, and CrCC samples, respectively.
The present study contains the results of experiments carried out to determine the optimum technology of melting special steels and alloys in a AC plasma-arc furnace with a ceramic hearth (10-14) which shows that a decrease of the nitrogen content of the investigated materials takes place at the start of preliminary deoxidation (Figures 6, 7).
Some thermal property data was measured from the copper-bismuth alloy for comparison to the C83600 alloy data, Cooling curves were acquired from a bismuth- containing alloy before and after deoxidation treatment, This would provide an indication of the effect of deoxidation on solidification range.
The purpose of the present study is to compare some available extraction methods applied for 3D investigations of inclusions and clusters in steel samples obtained during the deoxidation process in laboratory experiments and pilot plant trials.
Since the slag contains unavoidably the oxides of metals with variable valence of the type of iron, manganese, titanium, etc, the oxidation--reduction processes taking place in electroslag remelting (this must be taken into account) should be accompanied by deoxidation of the slag pool during melting.

Previously, in melting molybdenum in vacuum and deoxidation with carbon it was necessary to maintain the carbon content in the metal at approximately 0.06% to produce a malleable ingot.
The lower campaign life is probably associated with a reduction of alumina formation from deoxidation of carbon and low alloy steels with aluminum.
