Project summary

Objective of the project

The goal of the project is, by using the advantages provided by superplastic treatment, to develop promising technologies and rigging for production of complex-profile spatial and sheet items from titanium aluminide based alloys (TiAl and Тi₃Аl).

Results

The result of the implementation of the project will be the creation of technologies ensuring:

- savings of material by a factor of 3 ё 6 due to use of materials with low specific weight, increase of coefficient of material use in blank, decrease of metal consumption of equipment and tooling;
- reduction of labor costs down in 5 times during production of precise blanks of above type due to decrease of labor cost of mechanical finishing, expenses of restoration of a die rigging;
- increase of quality of products owing to improvement of mechanical properties and reduction of metallurgical defects in blanks;
- deepening of integration of various weapons designers into international scientific community through joint search for solutions in resource-saving technologies for the companies of the USA and European Community.
