15th WCIC Agenda
1:00 p.m. – 1:30 p.m. Development of of Ni Based Superalloy with High Temperature Strength, Low Density & Excellent Castability for Turbine Wheel Yoshiki Kumagai, Daido Steel Co., Ltd. As automotive exhaust emission is strictly regulated all
over the world, higher fuel efficiency and cleaner exhaust gas in combustion engines have been required. Recently, downsized engines combined with turbocharger have been one of effective solutions to improve fuel efficiency. To improve combustion efficiency, an exhaust gas temperature is increasing, therefore higher temperature resistance is especially required for turbine wheel in turbocharger. IN100 is one of the candidate alloy as it has high temperature properties with low density. However, it has low castability due to poor ductility at high temperature. In this study, the balance of Al and Ti composition was optimized from IN100 to improve the high temperature ductility by expanding the γ single phase region below the solidification temperature, while obtaining the high temperature strength by maintaining the volume fraction of γ’-Ni3(Ti,Al) phase equivalent to IN100 around 1000 °C. Furthermore, the high temperature creep rupture life increased by adding a small amount of Ta. The developed alloy was successful to produce the turbine wheel without surface crack and misrun. Thus, the developed alloy in this study has high castability, low density and high specific strength at high temperature. This alloy is being commercialized as a new turbine wheel material by Daido Castings Co., Ltd., and the evaluation has been proceeding by customers for the near-future applications.

SHELL-O-MATIC Customized and Fit for Purpose Shellroom solutions
Help Investment Casting Customers achieve and sustain top quartile performance by providing Innovative, Performant, and Reliable solutions to their operational challenges in the Shellrooms.
1:30 p.m. – 2:00 p.m. Ceramic Foundry Cores by 3D Printing Richard Gaignon, 3DCERAM Sinto Within U3DC, 3DCERAM and Avignon Ceramic are
developing a new 3D printing process for the production of ceramic foundry cores for turbine blades. This new approach enables us to make without moulds and other tools, and to manufacture “complex” cores in one piece. The other advantage is that the rest of the manufacturing stages of a blade remain unchanged compared with CIM.
