Project summary

Presented project belongs to the category of applied studies in the field of preparation of metals and alloys with improved characteristics (ISTC code – MAT-ALL). The project is to elaborate regimes for thermomechanical treatment of some alloys on the Ti base – providing the maximum manifestation of the shape memory effect (SME), superelasticity (SP) and damping properties (DA).

Objects: studied will be some Ti based construction and binary alloys as well as alloys with improved component and concentration composition which should be prepared during the course of the project. The alloys with improved properties will be prepared with consideration of the needs of the Institute of Cosmic Constructions of Georgia set for materials aimed for use in cosmic and land based transforming systems, in particular antenna.

According to the project a mini catalogue of Ti based alloys with indication of optimum regimes for thermomechanical treatment for all materials with shape memory effect, superelasticity and damping properties (thermal treatment for getting initial state, temperature and level of initial deformation, shape restoration level and temperature interval for the effect, return strength, limits of deformation level for superelastic behaviour, main damping parameters).

The scope of works will include: smelting of alloys, preparation of samples; initial thermal treatment for attaining required phase composition; study of temperature and concentration dependence of elastic properties; identification of the temperature of commencement and completion of direct and reverse ” martensite transformation; identification of temperature interval for direct, reverse and reversible shape memory effect; return strength; study of dependence of the parameters from component, concentration composition of alloys and deformation level; study of the mentioned parameters for superelastic and vibroabsorption behaviour of alloys. Based on obtained results alloys with new doping level, improving non-plastic behaviour will be prepared.

Used will be experience gained by participants in the field of metalscience, in particular in studies of nonelastic behaviour of Ti based alloys. Some results have been published in scientific editions, some protected by copyright (certificates issued by the Committee on Inventions and Discoveries of the USSR).

Accomplishment of the project will help weapon scientists of participating institutions to apply their skills and knowledge for development of technologies for “peaceful” purposes, support transition to market economy.

The role of foreign collaborators will consist in exchange of information, discussion of results and consulting. In some cases they may double-check the most significant results.

Results will be presented on quarterly basis and annually. The final report will be prepared.

Some of the most interesting results may be protected by copyright certificates.


The International Science and Technology Center (ISTC) is an intergovernmental organization connecting scientists from Kazakhstan, Armenia, Tajikistan, Kyrgyzstan, and Georgia with their peers and research organizations in the EU, Japan, Republic of Korea, Norway and the United States.


ISTC facilitates international science projects and assists the global scientific and business community to source and engage with CIS and Georgian institutes that develop or possess an excellence of scientific know-how.
