1. Strength Characteristics of Titanium Iron
Industrial grade FeTi70: Tensile strength 1454-1528 MPa, compressive strength 2390-2533 MPa (containing 65%-75% titanium).
General titanium alloy: Tensile strength range 686-1764 MPa, with specific strength superior to steel.
Strengthening mechanism: The TiFe strengthening phase and β-Ti dendrites synergistically improve plasticity (deformation 28.7%-37.4%).
2. Miscibility of Titanium and Iron
Alloy formation: Titanium-iron alloys contain 10%-50% titanium, with iron content adjusted as needed. Alloys containing 90% titanium are termed "industrial titanium iron".
Compatibility: Titanium enhances the strength of the iron matrix through solid solution strengthening, but carbon content must be controlled at high temperatures to prevent brittleness.
3. Core Uses of Ferrotitanium Powder
| field | Specific applications |
| metallurgy | Steel deoxidizer/Degassing agent fixes carbon and nitrogen elements; welding rod coating improves weld strength. |
| New Energy | Sodium ion battery negatve electrode (FeTiO₃Composite materials), hydrogen storage alloys (cycle5000Second efficiency＞95%). |
| Special Industry | Metal thermal reducing agent to produce other alloys; color additive for fireworks (colorful effects). |
4. Manufacturing Process of Ferrotitanium
Mainstream methods:
Aluminothermic method: Rutile (TiO₂) reacts with aluminum powder to produce FeTi70, with aluminum ≤5% and silicon ≤1.5%.
Direct reduction in rotary kiln: Titanium concentrate + non-coking coal yields ilmenite (FeTiO₃) at 1200-1400°C.
Purification process:
Four-step method: Ilmenite → high-titanium slag → titanium tetrachloride → sponge titanium → molten titanium ingot.
Key reaction: TiCl₄ + 2Mg → Ti + 2MgCl₂ (displacement reaction).
