Major Scientific Advances.


S. Dubinskiy in a group of Plastic deformation of special alloys department and Laboratoire sur les alliages à mémoire et systèmes intelligents (ETS, Montreal, Canada) participated in determination of nanostructure influence on static and fatigue functional properties of Ti-Ni- and Ti-Nb-based shape memory alloys (SMA), in determination of thermomechanical treatment influence on structure of these alloys and in development of thermomechanical regimes for nanostructures formation, which correspond to optimal combination of functional properties in Ti-Ni- and Ti-Nb-based SMA.

He participated in development of Ti-Nb-based SMA foam material for biomedical application. S. Dubinskiy presented oral presentations of international scientific conferences: ESOMAT 2009, ICOMAT 2011, THERMEC 2011, ESOMAT 2012, SMST 2013, ICCMNM 2013.

He developed, tested and successfully used in research a special loading module with actuator from thermomehanically treated Ti-Ni SMA for low-temperature thermal chamber “TTK450” of “PANanalitical X’Pert PRO” diffractometer.

This module allowed performing of an in situ X-ray diffraction analysis of Ti-Nb-based biomedical shape memory alloys under variable stress-temperatures conditions and determinate phase transformation features in Ti-Nb-based SMA under load.

Presentation of the results obtained using this module aroused great interest among the participants of international conferences ESOMAT 2012 and SMST 2013.
