Metallic Glass Matrix Composites III Book of Abstracts | Book Publisher International

The new class of materials is metallic glass matrix composites, and this area is rapidly developing from its predecessor, bulk metallic glasses. It nicely overcomes and fixes the problems provided by the former to enter a new class of enhanced strength, elastic strain limit while maintaining strength and hardness. This monograph is a collection of abstracts presented at the Third Series Conference that originally began in Columbus, Ohio, two years ago. Since then, several new experiments have appeared and much progress has been made in both theoretical / simulation studies and experimental work. The goal was to construct a full-scale component with complicated geometry with superior properties. This book contributes a lot to this end. Talks are divided into two sessions according to their author's topic, scope, and area of expertise. Further, an attempt has also been made to pinpoint future paths and potential evolutions. We hope that this symposium will serve as an emerging and ongoing forum to serve the needs of this community, extend it, and help realise the dream of using these materials to solve complex engineering issues. We remain on the sponsors' platform, Eastern Engineering Solutions LLC.

Research on the Simulation of Solidification Parameters during Zr Based Bulk Metallic Glass Matrix Composite’s (BMGMCs) Additive Manufacturing | Chapter 6 | Recent Developments in Engineering Research Vol.4

 

After a silence of three decades, bulk metallic glasses and their composites have re-emerged as a
competent engineering material owing to their excellent mechanical properties not observed in any
other engineering material known till date. However, they exhibit poor ductility and little or no
toughness which make them brittle and they fail catastrophically under tensile loading. Exact
explanation of this behaviour is difficult, and a lot of expensive experimentation is needed before
conclusive results could be drawn. In present study, a theoretical approach has been presented aimed at solving this problem. A detailed mathematical model has been developed to describe solidification phenomena in zirconium based bulk metallic glass matrix composites during additive manufacturing. It precisely models and predicts solidification parameters related to microscale solute diffusion (mass transfer) and capillary action in these rapidly solidifying sluggish slurries. Programming and simulation of model is performed in MATLAB®. Results show that the use of temperature dependent thermophysical properties yields a synergic effect for multitude improvement and refinement simulation results. Simulated values proved out to be in good agreement with prior simulated and experimental results. There is significant effect of initial metal temperature, composition, type of alloying elements,temperature gradient and thermo-physical properties on final microstructure developed as a result of heat and mass transfer phenomena.
