Summary

Super bainite, a surprisingly-strong steel, is the subject of this week's Naked Scientists. We discover how it's made in the metallurgical equivalent of a pizza oven, why it makes the best bearings and how, even when it's full of holes, it also makes great armour. In the news, a nanotechnological tool to unblock blood vessels, a dust cloud that's disappeared around a nearby star and have we found the Higgs? Plus, can your cutlery affect the flavour of food?

Stripping down science, the naked scientists.

The Naked Scientists. Steel is everywhere as one of the most versatile metals we use it in everything from

0:26.9

bridges and buildings to bicycles and bracelets, but how can we make it even better?

0:32.0

I'm Ben Valsler.

It's Sunday the 8th of July

0:35.0

and today we'll hear the story of Super Bayhight,

0:38.0

a super strong steel.

0:39.0

We'll hear how this new wonder material is great for a range of properties including the

0:43.7

bearings in wind turbines and solving the age-old problem of making good armor.

0:48.6

The other thing I was found quite intimidating about armor is you're up against Leonardo da Vinci

0:54.2

because he invented a bullet and in terms of opposition a da Vinci design is not easy to

0:59.2

defeat you'd be dead five hundred years and still cause in trouble. That's all coming up along with news of a new

1:04.8

nanotechnological way to bust blood clots and of course a look at the Higgs bosom.

and centuries of trial and trial and error bucket chemistry has given us a wide range of steel

alloys that are capable of performing almost every task that we set. So it might

surprise you to hear that steel can still surprise us with previously unthought of properties.
