Light alloys
Magnesium alloy castings – past and present Peter John Thompson
Castings Technology International. 67th World Foundry Congress
Magnesium is the lightest of the structural metals. Sand cast and HPDC Magnesium is used in a wide range of markets and applications, from automotive to aerospace. In all cases, weight saving is the primary reason for using Magnesium alloys. Precision cast Magnesium is not in widespread use. Main reason for this lies in the potential reaction of molten Magnesium with Silica found in most shell moulds. Recent work has shown that by modifi...

Advanced simulation techniques
3D-Numerical simulations of squeeze moulding with the finite element method Jürgen Bast / Abdulkader Kadauw
Technical University Bergakademie Freiberg, Germany.66th World Foundry Congress
Clay-bonded mould sand is widely used in the foundry industry due to its environmental and financial advantages. Sand compaction plays an important role for the quality of the mould and therefore for the quality of the casting. The determination of optimal compaction parameters is often carried out by trial-and- error-method, which is expensive and time consuming. To improve this situation, the process of compaction is modelled here by se...
