This special issue includes selected papers from the third Japan-Korea Workshop for Young Foundry Engineers (YFE). The third Japan-Korea Workshop for YFE was held at Nagasaki University in Nagasaki, Japan on October 16-18, 2009. Following the tradition of the previous workshop held in Korea (April, 2003 and June, 2005), the third workshop aims to provide the researchers in both academic and industrial arena to promote and exchange the principles and interdisciplinary understanding of resent achievements in solidification and casting fields. This workshop, in particular, emphasizes to build upon the international communicative competence among young participants through the lively discussion of innovative solidification and casting ideas. This workshop has been jointly supported by the Japan Foundry Engineering Society and the Korean Foundrymen’s Society. The third workshop was attended by about 100 academics, researchers and industrialists who belonged to universities, technological research centers and companies. The workshop extended three days and consisted of 21 oral presentations and 24 posters.

Because of the new mathematical models with fast-tracked computer and the new analysis equipment such as synchrotron radiation, solidification and casting fields find itself on the edge of another revolution. These techniques guide the researchers to the definitive understanding of fundamental solidification theory and the optimization approach of cast materials and processing. In this workshop, experimental, theoretical, computational and application aspect for the casting and solidification processes was covered including; (1) Ferrous cast alloys, (2) Non-ferrous cast alloys, (3) Composite & joining, (4) New casting process and materials development, (5) Casting production and environment technology, (6) Modeling & simulation in foundry engineering, and so on. The variety of materials was examined by the advanced model theory and analysis equipment for the development of microstructures and mechanical performances. Mechanical properties in many non-ferrous cast materials, such as magnesium, titanium, copper, nickel and bismuth alloy, were improved in the third YFE, whereas the advanced casting processing has been emphasized for the traditional materials such as a ductile or gray cast iron and an aluminum alloy. Furthermore, some microstructural challenges and their applications for the intermetallic compound, the composite materials and the bulk grass as the advanced cast materials were discussed circumstantially from the standpoint of the thermodynamics, non-steady state kinetics and crystal growth regime.

Finally, on behalf of organizing committee, we would like to express again our sincere appreciations to the Japan Foundry Engineering Society and the Korean Foundrymen’s Society. It would have been impossible to have such a successful workshop without the tireless effort of the staffs of branches in Japan Foundry Engineering Society and Korean Foundrymen’s Society. Our goal of this special issue is to share the recent excitements and achievements and to gain new insights for casting science and technology. We wish that the useful and novel information selected in this issue will contribute to the future development of the solidification and casting technology.
