PROJECT TITLE:

Understanding the phenomena/mechanisms occurring during thermomechanical processing of β-Ti alloys and their influence on crystallographic texture

 

PROJECT ACRONYM:

TextMech

 

PROJECT SUMMARY:

The project objective refers to advanced investigation of specific phenomena/mechanisms occurred during thermomechanical processing of a new β-Ti (Ti-30Nb-12Zr-5Ta-2Sn-1.25Fe wt.%) alloy and investigation of correlations between processing conditions – activated specific mechanism - exhibited crystallographic texture.
The project execution shows high potential of finding new correlations between processing conditions and exhibited crystallographic texture and their results translated in new possibilities to manipulate exhibited physical/mechanical properties, resulting an enlarged potential of opening other scientific research directions and potential technological applications of β-Ti alloys. For example, gaining new understanding of the deformation kinetics (slip/twinning evolution with progress of deformation intensity) by exploratory experiments will permit to redefine the boundaries of the deformation mechanism maps in the parametric space of stress and strain. Also, gaining new understanding of the recrystallization kinetics (nucleation/germination/growth of recrystallized phase with progress of thermal treatment) by exploratory experiments will permit to redefine the boundaries of the recrystallization mechanism in the parametric space of temperature and time

PROJECT OBJECTIVES AND RESULTS:

The project's main objective refers to the advanced investigation of specific phenomena/mechanisms that occurred during thermomechanical processing of a new β-Ti (belonging to Ti-Nb-Zr-Ta-Sn-Fe system) alloy and investigation of correlations between processing conditions, activated specific mechanism, and exhibited crystallographic texture.
The following results are envisaged:
- Obtaining of a new β-Ti alloy (belonging to Ti-Nb-Zr-Ta-Sn-Fe system);
- Assay of slip/twinning mechanisms induced by the cold deformation processing;
- Assay of recrystallization mechanisms induced by the thermal processing;
- Assay of cold deformation processing influence on texture development in Ti-Nb-Zr-Ta-Sn-Fe alloy;
- Assay of recrystallization processing influence on texture development in Ti-Nb-Zr-Ta-Sn-Fe alloy;
- Results dissemination in international scientific conferences and by publications of scientific papers (in ISI journals)
