Using digital quantitative image analysis system, effects of variation of equivalent area diameter and average area fraction of primary Si phase in different positions and Si particle diameters in super slow speed die casting hypereutectic Al-Si alloy on tensile strength and hardness of the alloy were investigated. The results reveal that with increasing in wall thickness, equivalent area diameter and equivalent area fraction of primary Si phase are increased. In addition, with increasing in equivalent area diameter, mechanical properties of the die casting hypereutectic Al-Si alloy is obviously improved.

In this investigation, the specimens were obtained from practical Al-15.5% Si (ADC14) aluminum alloy die castings, and their stress-strain curves from in-situ tensile test were investigated. The effect of Si particle and intermetallics on the crack initiation and propagation were analyzed and discussed. The results show that the cracks of the ADC14 alloys primarily initiated at the notch area, the phase interface between intermetallics and α-Al substrate, and the second phase particles. Gradually with the increase of loading, the second phase particles fractured and separated from α-Al substrates. The crack propagation was characterized along with the brittle phases and the interfaces between eutectic Si and α-Al phase and hence those microcracks result in macrocracks until the specimen fracture.

Fracture samples were prepared from different positions in practical fatigue failure ADC1 castings, and surface morphology and characteristics of the fracture samples were analyzed by SEM (scanning electron microscope) and EDS (energy dispersive spectrometry) to understand origination of fatigue failure of the castings. The results show that there exists pore with a larger size near surface and congregation of large area oxide film in the casting, which are responsible for the fatigue failure of the castings. In addition, the role of pore and oxide film in the process of failure was described.

The basic elements for die casting company to develop customers and products on high level were described. The developing history of a typical die casting company from small size up to median company was expounded, and some common experiences those could be useful for median-small size enterprises were described. In addition, the general process to develop high-level products on engineering and the basic strategies to be trusted by customers were presented. ©, 2015, Journal Office of Special Casting and Nonferrous Alloys.
