Super Bainite: Super Strong Steel
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?
