9:15-10:15 a.m. Modeling and Experimental Char- acterization of the Deformation of PUCB Sand Cores During Casting (17-068) Hiba Bargaoui, Farida Azzouz, Georges Cailletaud, Mines ParisTech, PSL Research University (Evry, France); Delphine Tibault, Montupet (Laignev- ille, France)
Understanding core deformation
would allow significant savings on development costs in corebox design and the full casting process. In this session, a new insight into core deformation will be given. A specific model involving resin aging and damage development is being devel- oped to represent the deformation as a function of load and temperature history.
Effect of Alloying Elements on the Performance of 354-Type Alloys (17-090) Guillermo Garza-Elizondo, Agnes M. Samuel, Fawzy Samuel, Université du Québec à Chicoutimi (Chicoutimi, Quebec, Canada); Hany Ammar, Suez University (Suez, Egypt); Salvador Valtierra Gallardo, Nemak, S.A. (Garza Garcia, Mexico) In this study, the effects of Ni,
Mn, Zr, and Sc additions, individu- ally or in combination with other additives, on the microstructure and tensile properties of 354 cast- ing alloy (Al-9wt%Si-1.8wt%Cu- 0.5wt%Mg) were investigated.
Effectively Communicating with Millennials (17-149) Mackenzie Meekhof How can you integrate young,
technology-driven talent into your foundry? Te first step is learning how we think, how we approach problems and our expectations. Te second step is learning how to bridge the differ- ences between your millennials, gen Xers, and boomers.
Effect of Austenite Fraction on Rare Earth Grain Refinement (17-083) Robert Tuttle, Saginaw Valley State University (University Center, Michigan) Several different rare earth oxides
can form. Most are excellent nuclei for austenite, but not ferrite. Plain carbon steels solidify by initially forming ferrite and then forming austenite through the peritectic reaction. Once austenite formation starts, the rare earth oxides which had not been a good fit for ferrite could nucleate aus- tenite. To examine how the austenite fraction during solidification effects grain refinement response, a series of plate casting experiments were con- ducted. Additions of rare earth silicide were made to form rare earth oxides. Grain refining response improved with an increase in austenite fraction during solidification.
10:30-11:30 a.m. Hoyt Memorial Lecture Te Power of and Need for Research in Metalcasting (17-148) Doug Trinowski, HA International LLC (Westmont, Illinois)
Past metalcasting research has led to measurable improvements in the industry. It focuses on the need for continued research as supported by AFS, along with several examples of critical needs and challenges in the industry that can only be resolved through organized research. This lecture will compare and
contrast how research is conducted in other countries, primarily the European Union. Finally, the need for improving the technical transfer process, taking fundamental research and commercializing it to improve the competitiveness and sustainabili- ty of the North American metalcast- ing community will be discussed.
11:30 a.m. President’s Lunch and Annual Business Meeting
Join the annual meeting where the election of AFS officers and directors will be announced. In ad- dition, the AFS Awards of Scientific Merit, Service Citations, Casting of the Year, Corporate Contribu- tion Award and Millionaires Safety Award will be presented. (Ticket required.)
