The effect of Fe element on the corrosion behavior for the Ti-30Zr-5Al-3V-xFe alloys was studied using potentiodynamic polarization curves. Fig. 5 shows the typical potentiodynamic polarization curves in 3.5% NaCl solution.
The effect of the addition of Ti, V, Cr, and Mn on the magnetic properties of a nanocrystalline soft magnetic Fe–Zr–B alloy has been investigated. The addition of the elements increases both the crystallization temperature and the grain size of α-Fe. After crystallization, these elements are observed in both the α-Fe grains and the residual amorphous matrix.

The behavior of Ti-Fe-Mn specimens under conditions of sintering at temperatures above the eutectic point is analogous to that of Ti-Fe and Ti-Fe-Ni specimens: The changes in the linear dimensions of compacts and the magnitude of exothermic effects depend on the rate of heating to the sintering .
The effects of the FeO content of original ores on the FeO content in sinter and the creating ability of calcium ferrite are discussed in this paper. The results show that the content of FeO in sinter of hematite is much lower than magnetite. ... Effect of FeO Content in Ore on the Properties of Sinter ... "Effect of FeO Content in Ore on the ...
This type of Fe-Ti-oxide deposit dominated by ilmenite rarely contains more than 300 million tons of ore, with between 10- to 45-percent titanium dioxide (TiO 2), 32- to 45-percent iron oxide (FeO), and less than 0.2-percent vanadium (V).

ARTICLES . diamonds by FGM. The effects of Ti additive on the synthetic conditions, crystal color, crystal shape, surface morphology and nitrogen impurity concentration etc.
Conclusions. The temperatures of accelerated formation of intermetallic compounds in the Ti-Fe-Mn system correspond to the temperatures of sharp changes in the direction and rate of the sintering process and also of the appearance of heat evolution peaks.
Abstract. The ratio of ilmenite (FeTiO3) to titanium dioxide (TiO2) was varied to synthesize Fe-TiC composites by carbothermal reduction of ilmenite ore under gas atmosphere at the temperature 1500°C.
The Fe activity was measured through the catalase and peroxidase enzymes and the active fraction of Fe (Fe 2+) and Ti was determined in leaves, fruits, chloroplasts and chromoplasts. chat online Iron (Fe) - Chemical properties, Health and …
Effect of iron content on sintering behavior of Ti-V-Fe-Al near-beta titanium alloy Abstract Two near-beta Ti-10V-3Fe-3Al and Ti-10V-2Fe-3Al alloys were produced by blended elemental powder
May 14, 2009· Fe Content: Iron of as high-grade as possible is required because an increased of 1% Fe in the burden increased the productivity by 2% and decreased the coke rate by 3%. In the THB Mining, the range of the Fe content in iron ore lumps is 60.52% to 66.5%.

The volume shrinkage value of the reduced Ti–Nb-bearing Fe concentrate/coal composite pellet with a basicity of 1.0 was approximately 35.2% when the pellet was reduced at 1100°C for 20 min, which enhanced the external heat transfer to the lower layers when reduced in a practical rotary hearth furnace.
From Fig. 1 and Table 3, with the increase in the content of B 2 O 3 from 1 to 3 mass-%, the area of liquid phase in each sample increased dramatically from 53.2 to 90.2% at 1573 K for 10 min.
