The discovery of bulk metallic glasses (BMGs) has stimulated widespread research enthusiasm because of their technological promise for practical applications and scientific importance in understanding glass formation and glass phenomena. Arising from their disordered atomic structure and unique glass-to-supercooled liquid transition, BMGs represent a new class of structural and functional materials with extraordinary properties including extreme strength and high elastic limits, along with several superior chemical and physical properties. Moreover, the BMGs have been recently used in a wide range of engineering applications such as soft magnetic materials and catalytic materials, solder, and magnetic sensors or biomedical implants.

There are many unresolved concerns for further research and studies. To provide some examples, the identification of the relaxation phenomenon and its relation to the physical and mechanical properties have remained a long-lasting challenge for researchers, engineers, and developers. Furthermore, the random atomic arrangement makes it difficult to predict and evaluate plastic deformation, mechanical behavior, and physical properties in the BMGs. Hence, the structural characterization and mechanical evaluation of BMGs play a crucial role in their design and development for engineering applications.

This Special Issue welcomes original research and review articles on a rich variety of research topics, including the characterization and processing of BMGs applied as engineering materials. We encourage experienced practitioners and scientists from all over the world that design novel glassy compositions and evaluate the inherent features of MGs, from physical properties to mechanical behaviors.
