Preliminary scope of work
Titanium alloys have been attracting an increasing interest in the aerospace, automotive and chemical industry due to their outstanding physical properties. Titanium alloys stand out primarily due to their high specific strength and corrosion resistance. Moreover, a number of titanium alloys are biocompatible, which makes them ideal candidates for applications in medicine (e.g. hip joint implants). A prospective group of these alloys are the so-called metastable beta titanium alloys which exhibit a set of complex phase transformations which can be employed to improve the mechanical performance of the material. Some of the mechanisms of these phase transformations have not yet been fully understood. Therefore, it is of a great interest to study them theoretically. The aim of this work will be to propose a theoretical model describing selected phase transformations in metastable beta titanium alloys and to test the validity of the model against experimental results.
