Bulk metallic glass matrix composites have remained the focus of very recent attempts to improve toughness in otherwise placid brittle glasses. Various previous studies have shed light on adoption of new methodologies and techniques to achieve this objective. These include; use of computationally intelligent algorithms, machine learning, alloying (Yt, Si, Rare earth, Ce, Ta, Au, Ag, W, Gd, Er, Metalloid), microstructure tuning, characterization (in-situ techniques, ultrafast calorimetry, step scan modulated temperature differential scanning calorimetry, rotating cylinder rheometer, nanoindentation, neutron scattering and synchrotron studies), mechanical properties measurement, optimization and process innovation (thermoplastic forming, co-extrusion, powder metallurgy, torsion and additive manufacturing). However, newer and newer techniques and mechanisms have been proposed which are increasing the spectrum of these materials, broadening our understanding about them and increasing their importance and various applications.
Objective of this symposium is to invite enticing, intriguing, though provoking, motivating and inspiring talks from active researchers in this field which will further help in building a detailed knowledge base about these materials and manufacture parts and components from them. Special areas of focus will be;
1. Thin film metallic glasses, composites and their importance.
2. Tuning of microstructure (including dendrite arm spacing control, phase transformations) for nuclear applications (including development of plasma facing materials) and by ion radiation (including Xe - ion).
3. Control of deformation mechanisms (e.g. by control of shear band (including torsion induced), size effect, interface, fragility, energetic frustration, reconstructed hierarchical processes, vibration induced accelerated aging and rejuvenation, surface rejuvenation, cryogenic rejuvenation, cryogenic temperature induced structural transformations, cryothermal cycling, poison ratio relation, thermomechanical induced creep induced rejuvenation, rapid and partial crystallization, tension – compression asymmetry and deformation induced heterogeneities, β relaxation, Johari – Goldstein relaxation, double stage structural relaxation, Gr neisen parameter).
4. Understanding crystallization kinetics, brittleness in phase separation, chemical heterogeneities, shear band – crack, invar effect, sub Tg annealing, elastic behaviour and yield strength, cyclic loading, bending, hyperbolic expression, boson peaks and Von Hove singularities and development of universal structural parameter.
5. Improvement of glass forming ability and understanding its relationship with other parameters (e.g. thermal conductivity).
6. Employing new modelling simulation techniques (especially atomistic, molecular dynamics and phase field).
7. Promoting new processing techniques (such as spark plasma sintering, flash annealing, laser spike annealing, resistance spot welding, microgravity levitation, pneumatic injection 3D printing, additive manufacturing).
8. Probing new applications (such as magnetic refrigerants, gears, coatings, corrosion, tribocorrosion, wastewater treatment, electrocatalysis and biomedical). |
