Title: Metals
Url: http://www.bbc.co.uk/radio4/science/connect_20030716.shtml
Publisher: BBC Radio 4
Description: This radio broadcast reviews the evolution of metals since the discovery of copper in ancient times, and looks at how science and technology are continually upgrading the design and development of metal alloys. There are explanations of five ways the chemical composition of an alloy can be modified to produce different properties; how heat treating is used to process metals; how mining metals can be sped up by microwaving metals; how metals are deformed to test them for structural properties; and how nano-crystalline alloys are designed using computer models to find the best chemical composition and processing parameters with minimal experimentation. The broadcast is 30 minutes in length.
