What is needed in the market?
Brief technology description
Stage of development
Who needs it & how many will they need?
What is my unique technology advantage?
How will I beat the competition?
Opportunity for joint work
Titanium alloys are attractive construction materials to use in aerospace, automotive and other industries due to:
But: Wider application of these materials is limited by their relative high cost: $15/kg (titanium sponge), up to$150-200/kg (components)
The main trend in titanium materials science is to
expand application of titanium alloys bydevelopment of new technologies that provide significant cost reduction
Ti, Alloying Elements Powders
Up to 90%
Low Porous Part
99+%Brief Technology Description
Powder metallurgy enables significant reduction in the cost
Blended elemental powder metallurgy approach is potentially the lowest-cost process, especially if additional working operations (HIP or hot deformation) can be avoided.
Sintered densities of TiH2 blends:
- higher than in equivalent Ti-based blends
- do not noticeably depend on molding pressure
ArgonCost-Effective Production of Hydrogenated Titanium Powder
Production in Ukraine:
Zaporozhje Titanium&Magnesium Plant
Proposed PM technology: cost of parts 1.4-2 S (per kg)
Conventional PM approach(CHIP): cost of parts 5-10 S
World production per year : 53 million vehicles 212 million conrods
- Aerospace industry (components for non-critical application)
- Medical applications, etc.
1. Other titanium PM technologies(CHIP)
- expensive starting powders with low impurity content
2. Ingot metallurgy
- multistep manufacturing
- low material yield
Purpose: application of developed technology in automotive, aerospace and medical industries
