Microstructure of the extruded aluminium AlSi9Cu3(Fe) machining chips reheated in the semisolid state

The main aim of this research was to prepare quality thixo feedstock directly from aluminium alloy AlSi9Cu3(Fe) machining chips waste. The main condition to produce thixo feedstock is globular microstructure formation during heating at the semisolid range. Machining chips were cleaned, compacted and direct hot extruded in order to create dense compacted samples. After extrusion samples were heated at the semisolid range and hold for a different time in order to determine a suitable time for globular microstructure formation. After heating at semisolid range samples were quenched in the water to preserve obtained microstructure. Metallography analysis was performed. Conclusion indicated that homogeneously dispersed solid globular primary aluminium surrounded with liquid eutectic phases can be produced directly from aluminium machining chips waste. Such process could be beneficial for lower energy consumption, higher material yield and therefore reduction of the greenhouse gases into the atmosphere.
