Improving the internal quality of aluminum alloy castings by the optimization of foundry technology

This master’s thesis deals with the topic of improving the internal quality of aluminium alloy castings using foundry technology optimization. Theoretical part of this thesis consists of five chapters. These chapters deal with topics of internal defects in castings, solidification of aluminium alloys, numerical simulations in foundry, feeding and use of chills. The second part of this thesis is experimental. It focuses on defect analysis of investigated castings, casting technology simulation and suggestions for its improvement, with consideration for liquid metal utilization
