“…Important examples include linerless engine blocks for passenger vehicles, motorcycle cylinder blocks cast using high pressure die casting (HPDC), and pistons using low pressure permanent mold (LPPM) casting processes [1][2][3][4][5][6]. Figure 1 shows a cross-section of a 250cm 3 motorcycle engine with a hypereutectic Al-20%Si cylinder block cast using the vacuum HPDC process.…”

“…For example, cast components that experience service conditions of high temperature and load, such as engine blocks, are now routinely produced using the Al-Si alloys [1][2][3][4][5][6]. It is understood that as-cast microstructure of the material is much dependent on melt processing in casting operations.…”

Over the last three decades the semi-solid metal (SSM) processing has received significant attention. Semi-solid processing involves the net shape manufacturing of alloys in the semi-solid state. The principal attraction for the process has been the unique rheology of the slurry which induces better movement of materials through the die and allows intricate thin-wall near net shape components to be cast at lower applied pressures. This behaviour offers considerable advantages to the quality of castings. The reduced oxide entrapment, low porosity and a lower operating temperature make semi-solid processing ideal for the forming of high integrity parts.The aim of the current study was to investigate the rheological behavior and microstructural evolution of hypereutectic Al-Si-Cu and Al-Si-Mg-Cu alloys using conventional and modified SEED process (Swirled Enthalpy Equilibration Device). This project is divided into four parts.
