The 2016 Van Vlack Lecture Series: Science and Technology of Metallic Glasses

William L. Johnson
Ruben F. and Donna Mettler Professor of Engineering and Applied Science California Institute of Technology

Metallic glasses are vitrified metal alloys – liquid alloys that solidify without crystallizing. Like silicate glasses and thermoplastic polymers, they exhibit a glass transition below which the liquid freezes to a solid that resists shear on practical time scales. Bulk metallic glasses developed over the past two decades, exhibit unique thermal, mechanical, and magnetic properties that make them an attractive choice for numerous engineering applications. Their glassy nature opens processing and manufacturing opportunities normally associated with plastics technology. The speaker will survey the scientific and technological evolution of metallic glasses from their inception to the present time. He will describe how metallic glass technology offers unique opportunities to change the way metals are used and commercial metal products are manufactured.



The Van Vlack Lecture Series was established in honor of L. H. Van Vlack, to provide a distinguished lecture series from the outstanding leaders in the field of Materials Science and Engineering
