||The objective of this symposium is to provide and increase fundamental theoretical and experimental understanding, and foresight of the methodologies adopted to solve longstanding debate of lack of ductility and toughness in these promising materials. These include; atomistic and part scale modeling and simulation, observation under synchrotron light and in microgravity conditions, machine learning, employing computationally intelligent techniques (e-g. support vector regression (SVR), artificial neural network (ANN), general regression neural network (GRNN), and multiple linear regression (MLR)), in-situ scanning and transmission electron microscopy observations, fracture toughness and additive manufacturing.
There has been tremendous interest observed in the development, processing and progress of these materials during past three decades. Main areas of focus have been;
a) Improvement of properties by alloying (e.g. ß stabilizers (Ta, Nb, V, Cu, Ni) or ß destabilizers (Sn and Al) and make an effort to eliminate Be).
b) Discover new alloying elements by machine learning.
c) Improve glass forming ability by use of computationally intelligent techniques.
d) Improving resistance to, or increase the number of, shear bands by improving length scale at which they interact or providing pivots to their motion and propagation.
e) Discover new algorithms based on plasticity (devitrification), solidification (classical nucleation theory and its modifications) and prediction of solidification microstructures by cellular automaton and phase field approaches and their variants (such as full field modeling).
A special focus and emphasis is led on new and rapidly evolving technique - additive manufacturing. It is hypothesized that a lot of promise exist in this to manufacture composite parts in one step eliminating the need of post processing. Discussion will be focused on explaining the advantages and disadvantages of this technique and lead strategies to approve this hypothesis. There is a lot of gap in understanding of fundamental science behind how a composite part can be formed by additive manufacturing? This symposium will try to answer these questions. Further areas of focus include;
a) Solidification microstructures during single layer additive manufacturing.
b) Solidification microstructures during double and multi-layer additive manufacturing.
c) Microstructures during re heating (devitrification).
d) Detailed qualitative and quantitative characterization of crystalline phases.
e) Thin films.
f) Control of processing parameters.
g) Process optimization, control and reproducibility.
