13th International Conference on Fracture June 16–21, 2013, Beijing, China -9- that in general the fracture mode is mixed between inter- and intra-granular. Additionally, at higher solid fraction, the morphology of eutectic is different at different displacement rates (Figure 8b and 8c). Sites that resemble necking of interdendritic liquid was observed at samples that were tested at lower solid fraction (Figure 8d), independent of displacement rate used during the test. Acknowledgment This research was carried out within the Materials innovation institute (www.m2i.nl) research framework, project number M42.5.09340. The establishment of the experimental set-up and testing procedure for the mechanical tensile testing in the semi-solid has been supported by the Norsk Hydro Fond for SINTEF. The authors would like to express their gratitude to Dr. Démian Ruvalcaba and Mr. Jacob van Oord (Tata Steel Research, Development & Technology, The Netherlands) and also to Mr. Hans I. Lange and Mr. Arne Nordmark (SINTEF Materials and Chemistry, Norway) for their support and inputs. Support from Modelling assisted INnovation for Aluminum DC Casting process (MINAC) community is highly appreciated. References [1] J.C. Williams, E.A. Starke Jr, Acta Materialia, 51 (2003) 5775-5799.
