About the course
Course content
Nucleation and grain refinement, growth morphology of crystals, stability of the liquid/solid interface, dendrites cells, and eutectic structures, micro- and macrosegregation, continuous casting processes and processes for shape castings, castability. Casting alloys. Modelling of solidification and casting
Learning outcome
After completing the course the student should be able to: - Explain basic concepts such as directed and equiaxed solidification, capillary effects, redistribution of alloying elements during solidification and various types of microstructure. - Explain the theory of nucleation, interface structures and morphological stability of the melt / crystal interface and be able to use this theory for simple calculations and prediction of microstructure types. - Explain basic theories for cell growth, dendritic eutectic and peritectural microstructures and be able to calculate simple morphological properties of these structures. - Perform salvage of micro-seeding and solidification paths. - Explain important continuous casting processes: continuous casting of steel, DC casting of aluminum, tape casting, Hazelett and Properzip process. - Explain important casting processes: sand casting, precision casting, castile casting, low and high pressure casting, melt pressing, lost foam and thixo casting and be able to explain the requirements for running, feeders, filters and explain the impact of melt quality. - Evaluate an alloy's castability and recognize important casting defects: fluidity, heat crack, macro-erosion and pore formation. - Explain the composition and properties of some of the most important cast alloys.
