Harry Bhadeshia and Alan Bagg appeared with the Naked Scientists (interviewed live on BBC Cambridgeshire) to talk about ‘Super Bainite’. and it’s potential applications for bearings A transcript of the interview can be read and the interview downloaded as an mp3. A seperate transcript is available for the part of the interview with Alan Bagg.
Later on in the program (around 45 mins–53 mins) there is an interview with Prof. Peter Brown about the use of Super Bainite as a armour. After which Harry and Alan field tweeted questions.
Photos of the BBC studio used for the interview can be seen on Harry Bhadeshia’s website.

My paper has received page numbers and been published on paper, it also now has a page on phase transformations website.
This strange video appeared discussing the so-called bainite controversy.

I’m very happy that my paper was accepted for publication in Metallurgical and Materials Transactions A. It took a long time from performing the experiment to presenting the results, mainly because I needed to repeat the analysis which was something I wasn’t able to make time for until I had to submit the thesis.
Surface relief caused by shear transformation of bainite
In the paper atomic force microscopy is used to measure the shear component of extremely thin plates of bainitic ferrite in superbainite. The shear component is surprisingly large compared to the value we expected of 0.23–0.28 based on previous experiments carried out after transformation at higher temperatures (such as the results by Swallow and Bhadeshia).
It seems like the higher strain may help to explain why the bainitic ferrite plates are so thin and slender. It would now be really interesting to test if that is true or not, which is something I couldn’t really do by looking at the TEM and SEM images I have already.
