Abstract Scope |
The glass problem is a major unsolved problem in the physical sciences, despite the ancient history of glass technology. Our understanding of many phenomena in glass science remains incomplete. The recent Nobel Prize awarded to Giorgio Parisi for his work on spin glass transitions underscores the importance of this research. While in spin glasses complexity is introduced by frustration of the spins, in structural glasses such as metallic glasses complexity arises from a variety of sources such as configurational, conformational or chemical origins. This complexity is associated with dynamic properties and affects physical properties such as elasticity and ductility. We will explore how measures of entropy derived from X-ray diffraction or molecular dynamics can link structural and dynamic relaxation mechanisms in metallic glasses. In addition, we will examine the limitations of aging and rejuvenation approaches and demonstrate practical applications, such as controlling energy input during additive manufacturing of metallic glasses. |
