Scope The objective of this symposium is to provide scientific community with an introduction to, and sound base and further insight for the understanding of bulk metallic glasses and their composites. Over a period, many studies have been carried out engulfed around understanding mechanisms of formation of these materials by various modeling and simulation and experimental techniques. However, still there is research gap in understanding how glass is formed, what is its nature, what is glass forming ability, how it can be improved, what is rejuvenation (mechanical and thermal), what is relaxation, how composite structure is formed, how crystallization could be tuned, how it could be studied and how it effects final properties? These a few of many open research questions. Aim of present symposium is to provide an answer to these.

A new class of sulfur bearing metallic glasses is also introduced. These encompass superior properties such as enhanced glass forming ability and refined microstructure. A special focus is laid on embrittlement and brittleness in metallic glasses, difference, evolution and ductile to brittle transition. Light is also shed on understanding sample size and its variability and method of testing (indentation, impact or bending (mode I, II and III)) on fracture toughness. A special section is dedicated on hall-petch like relations developed for bulk metallic glass matrix composites to quantify mechanical properties.

Focus areas are;

- Glass formation and its nature (thermodynamics, ordering, its range and transitions)
- Alloying elements (Al, S, Ag, Mo)
- Microstructure tuning (nucleation starvation, copious nucleation, nanoscale heterogeneity, metastability and iteration)
- Deformation mechanisms (in-situ studies, shear bands, slip avalanches, dynamics, heating), brittleness and fracture toughness
- Fatigue, creep, torsion, corrosion and tribology (friction, erosion and wear)
- Advanced characterization (including synchrotron, neutron scattering, ultrafast calorimetry and micro and zero gravity experiments)
- Advanced forming (thermoplastic forming, co-extrusion, powder metallurgy (including plasma sintering) and Additive Manufacturing / 3D printing)
- Modeling and simulation (macroscopic part scale, microscopic and atomistic) and machine learning
- Extreme (including cryogenic and irradiation) engineering applications
