MATERIALS SCIENCE AND ENGINEERING SEMINAR Macrosegregation and Shrinkage Pipe Formation in Static Castings By: Sailei Zhang Ph.D. Final Examination Co-Advisors: Prof. M. J. Krane and Prof. D. R. Johnson ABSTRACT Both macrosegregation and shrinkage defects are common problems in static castings. However these two aspects were usually studied separately in earlier research. In this presentation, a single-domain multi-phase model is developed for macrosegregation evolution and shrinkage pipe formation in static castings, as functions of buoyancy- and shrinkage-induced flow. Using a volume-of-fluid (VOF) method, both the air/liquid and air/solid interfaces are tracked during shrinkage pipe formation. The model is applied to binary Ti-48Al (at.%) and ternary Ti-46.6Al-8.6Nb (at.%) alloys in a cylindrical mould (R = 3.5 cm, H = 15 cm). Experiments to investigate macrosegregation and shrinkage pipe formation are performed by casting both alloys in an induction skull melting (ISM) furnace, using tilt-casting method in investment moulds. No significant exchange of fluid that is not at nominal composition between the riser and the part is found. However, the macrosegregation level is increased in a larger scale casting (R = 30 cm, H = 50 cm), which can potentially change the primary solidification phase and the local microstructure of the γ-TiAl alloy in the final cast. To study the influence of the riser on flow exchange between riser and cast part as well as the macrosegregation development in static castings, an Al-5wt. % Cu alloy system is used. An ingot with the riser designed based on Chvorinov's rule is performed in a slab mould, which is used as a standard case for this study. The results show that a wider riser is able to provide a barrier and prevent the solute-rich interdendritic liquid in the riser from flowing into cast part. For the castings with the riser shape being fixed, the average composition in the cast part is smaller at a higher solidification rate. Date: Thursday, April 18, 2013 Time: 9:30 A.M.

The school will be held August 19-30, 2013, at the University of California, Santa Barbara. The participants in this summer school are senior graduate students who work in the relevant areas, and are drawn from the US and internationally. Boarding and lodging costs are covered for all participants. Travel costs are covered for speakers and partial travel is given to students to offset some of the cost. The school is largely supported and run by UCSB and NSF-supported International Center for Materials Research ( www.icmr.ucsb.edu ). We welcome applications for the Summer School from graduate (PhD) students, post-doctoral fellows, and early career faculty in Materials Science and Engineering and allied disciplines with an interest and understanding the structure and behavior of complex inorganic and alloy materials across multiple length scales. To learn more and to apply, please visit the following website: http://www.icmr.ucsb.edu/programs/upcoming.html The deadline for applications is May 15, 2013. Notes : If you are a postdoc, let me know if 1st or 2nd year. Make sure to submit the attachments below with your application - A One page CV - List of publications - Letter of recommendation Thanks, Marisol -- Marisol Cedillo Dougherty International Center for Materials Research (ICMR) University of California, Santa Barbara MRL Bldg, Room 3019 Santa Barbara, CA 93106-5121 Ph: (805) 893-2637 Fx: (805) 893-8797 email: marisol(a)icmr.ucsb.edu
