The analysis indicates that matching the relation among the pH value, iron concentration, oxidizing activity and radox potential was the key to keep Fe~(3+) deposition least, on the base of bacteria adapting lower acid.关键词: bioleaching Fe~(3+) deposition copper ore thiobacillus ferrooxidans ...
The elucidation of the deadman's behavior and the interaction between slag–iron–coke within the blast furnace hearth are essential for the realization of low‐carbon and safe production. In this review, the macrostate of the deadman, the interactions between slag–iron–coke,...
Passivity of iron is due to a thin, nonporous surface layer of iron oxides which exhibits increasing iron deficit with increasing distance from the metal/oxide interface. Ellipsometric and coulometric investigations of the layer thickness and stoichiometric composition, in conditions of anodic polarization...

We find the oxygen abundance trends of thick-disk and high-alpha halo stars very similar. The low-alpha stars show a larger star-to-star scatter in [O/Fe] at a given [Fe/H] and have systematically lower oxygen abundances compared to the other two groups. Thus, we find the behavior ...
The corrosion of low alloy steel and stainless steel in the dynamic supercritical CO2/H2O/H2S system was studied. A Cr-containing scale, mainly consisted of FeCO3, Cr(OH)3and iron sulfide (mackinawite), formed on low alloy steel. FeCO3formed via the solid state reaction and precipitation react...
Microalloyed steels are in high demand in industries, including oil and gas transportation sectors as well as automobile industries. Alloying elements affects the phase transformation behavior during processing and ensues better mechanical properties1,2,3. Demand by the oil and gas transportation pipeline...
