| Abstract Scope |
Metastable β-Titanium alloys offer wide range of processability, multiple microstructures and hence, impressive mechanical properties. A β-solutionised microstructure may be aged below or above the ω solvus temperatures for either a short-term or a long-term heat-treatment. The effect of plastic deformation (cold-rolling) prior to such heat-treatment has also been realized recently. Large tonnage commercial usage of these alloys for safety critical applications makes such observations important as they may help design more robust and economically efficient processing routes. In the present talk, we discuss some of these approaches which lead to substantial increase in yield strength without any significant compromise to strain-hardening or ductility. Using experiments in commercial alloy systems coupled with DFT studies in modal binary beta-Titanium alloys we show how to realize this goal and with detailed investigation of the associated deformation-mechanisms we provide insights for a wider application of such approaches. |
