What is it about?
The paper analyses specific defects of castings produced by semi-solid casting process, especially rheocasting method SEED, which uses mechanical swirling for reaching proper structure in semisolid state with high content of solid fraction. Heat treated alloy AlSi7Mg0.3 was applied for producing an Engine Bracket casting part. For observing structure, metallographic observation by light and SEM microscopy was used. To analyse the process, software ProCAST was used to simulate the movements in shot chamber and filling of the mold.

Why is it important?
The work shows practical problems and their solving possibilities in such a specific area as rheocasting.
Perspectives
Rheocasting is perspective foundry technology producing shape complex, good inner quality and high performance castings, so speaking about problems solving brings steps ahead.
