How the Crystallization Process in Metal Casting is Influenced by the Mold Filling and Cooling Methods

The paper presents a case study on a aluminium part obtained by three different casting methods: die casting, investment casting and sand casting. The article analyzes the mold filling method, solidification time and crystal structure type obtained for each casting process. The purpose was to obtaine more homogenous crystalline structure of the cast parts, with better mechanical properties. The mold filling method with molten metal and heat transfer method influences the mechanical properties of the cast parts.
