Burning Titanium

Event details

Titanium alloys are hugely valuable and widely used for their combination of light weight and high strength. They also have good corrosion resistance thanks to the formation of a thin oxide scale. Curiously, density functional calculations show that this scale is not thermodynamically stable. We tried the line "its no use pointing at it, the computer says it isn't there", but this didn't wash well with our metallurgist colleagues. So we devised a non-equilibrium model to describe the process which, as these things do, turned out to be very similar to work by Sugden and Evans. In this talk I'll present the background to phase stability in titanium, corrosion resistance, the loss of corrosion resistance at high temperature, and the ultimate failure of corrosion resistance: burning.

About Condensed Matter lunchtime seminars

This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
