Fundamental scientific concepts are aimed to be employed to metallic glass matrix composites. These range from observations of incipient small transitory cluster of atoms, to rise of liquid like regions in glass prior nucleation to delay time, shift of Tg and recent pikes observed in ultrafast calorimetry spectra. All these point towards existence of certain fundamental underlying scientific phenomena which may, or may not point towards formation and evolution of crystal phase from within glass (homogeneous nucleation) or after glass (heterogeneous nucleation) formation.

Lately, focus has also remained on employing theory to develop algorithms and carry out simulations (macroscopic part scale, microscopic, atomistic and machine learning) on large scale computing platforms. Further detailed experimentation on large scale experimental setups employing source of radiations (X-rays, fine x-rays, amplified, stimulated light and neutrons) helped reveal structure, discover new phenomena (liquid – liquid transitions, phase transformation, icosahedral and quasi crystals) and verify theoretical observations in a much better way. However, applications of these to metallic glass matrix composites is in its infancy and these will be discussed in present congregation in a much better, detailed and effective manner. A very brief discussion will also be carried out to understand the effects of alloying elements, glass forming ability, microstructure tuning and mechanical properties.
