B Project B4: Ti alloy development

Property/microstructure relationships are critical to the behaviour of Ti alloys. For any particular alloy the microstructure may be tailored to meet the specific requirements of the end application. It is recognised, however, that Ti alloys in general suffer from quench sensitivity and only a small number are considered to be deep hardenable as a consequence.

Currently, Ti alloys are deemed to be deep hardenable if the strength can be maintained at 95% of the UTS at a thickness of 100mm. There is a real need for this to be improved so that thicker section components can be produced. This project aims to address the problem of deep hardenability, looking at the fundamental mechanisms which control this behaviour.
