| Abstract Scope |
The hybrid casting process allows the manufacture of components of two materials with different chemical compositions and microstructures in the same mold, reducing the use of expensive materials. It also reduces processing time by reducing the need of machining, welding, joining, and finishing. The hybrid casting of ferrous alloys, such as steel and cast iron, is of special interest for the manufacture of large tooling for the automotive sector. The object of this study is a hybrid component made by a High Chrome Cast Iron and a low Carbon Steel, produced by full molding casting process. Using Thermo-Calc (with the DICTRA mode) software it was possible to predict the diffusion of elements at the interface. Solidification simulation shows that is viable to cast a hybrid component with no defects. The small pouring temperature difference combined with diffusion grants a robust and defect free interface. |
