Douglas Hofmann and Colleagues Create Titanium-Based Structural Metallic-Glass Composites

Visiting scientist Douglas Hofmann (MS '06) and and colleagues, including William Johnson, Ruben F. and Donna Mettler Professor of Engineering and Applied Science, have created structural metallic-glass composites, based in titanium, that are lighter and less expensive than any the group had previously created, while still maintaining their toughness and ductility--the ability to be deformed without breaking. They are among the toughest engineering materials that currently exist. [Caltech Press Release]
