| Course Objectives | Solidification science is of paramount importance not only in understanding macro- and microscopic changes during the solidification of castings, but is also the basis of many new processes and materials such as semi-solid casting, laser melting, powder atomization, metal matrix composites, bulk metallic glasses. Many of the processes used in metal casting are still empirical in nature, but many others are deep-rooted in mathematics. The acceptance of computational modeling of solidification by metal casting industry is a direct result of the gigantic achievements made by solidification science in the last 25 years or so. Foundry reports indicate that solidification modeling is not only a cost-effective investment but also a major technical asset. It helps foundries move into markets with more complex and technically demanding work. The ability to predict internal soundness allows foundries to improve quality and deliveries, and provides the information required to make key manufacturing decisions based on accurate cost estimates before pattern construction even begins. This course aims at analyzing the solidification and crystallization processes from a general point of view and in accordance with generally accepted results and experimental evidence of modern research in the field, and attempts to synthesize the information that can be used for engineering calculations pertinent to computational modeling of casting solidification, and fundamentals of rapid solidification and bulk metallic glasses. |
