Metallurgy - Metals at the Molecular Scale - Naked Scientists Enhanced Podcast 11.05.29

May 28th, 2011

Episode 343 of 1057 episodes

What happens when a blacksmith meets a metallurgist? This week we explore what's happening at the molecular scale when the smithy works a piece of iron, we meet the superalloys that survive temperatures way above their melting points inside jet engines, and at the Rolls Royce precision casting facility we discover how precision plane engine parts can be cast from a single metal crystal. Also, in the news this week, how the blind brain has a built-in sonar, an attractive new magnetic material turned on by a current, and a new technique to detect troublespots brewing inside arteries. Plus, Kitchen Metallurgy - an experiment to show how you can manipulate metal molecules for yourself!
