episode 247: Bulk Metallic Glass
Guest: Douglas Hofmann Host: Markus Voelter Shownoter: Alexander Grote
Dr. Douglas Hofmann works as a scientist in the Metallurgy Lab at NASA’s Jet Propulsion Laboratory. I visited Doug during my US trip earlier this year, and we chatted about metallic glass. In particular, we discussed its properties, how to create it in bulk, how to test its properties, as well as how and why it is interesting for use in space.
