Correlation between segregation behavior and wall thickness in a rheological high pressure die-casting AC46000 aluminum alloy

Rheological behavior of a commercial AA5182 aluminum alloy during solidification

During casting of aluminum alloys, the partially solidified material is submitted to thermally induced strains that can lead to severe casting defects, such as hot tearing. In this work, carried out in the frame of the European project VIR[CAST], the rheological behavior of a partially solidified AA5182 aluminum alloy has been investigated in order to provide constitutive equations to predict h...

High pressure die casting of Fe-based metallic glass

Soft ferromagnetic Fe-based bulk metallic glass key-shaped specimens with a maximum and minimum width of 25.4 and 5 mm, respectively, were successfully produced using a high pressure die casting (HPDC) method, The influence of die material, alloy temperature and flow rate on the microstructure, thermal stability and soft ferromagnetic properties has been studied. The results suggest that a stee...

Modern High Pressure Die-casting Processes for Aluminium Castings

There are about 33 processes commercially available for the production of aluminium castings. About 70% of the castings are produced using conventional high-pressure die-casting process. It’s main drawbacks are 1) Air and gas blow holes 2) Unable to weld 3) unable to heat treat to enhance mechanical properties. To overcome these, many modern processes have been invented. A few of them are 1) Hi...

Semisolid Processing of Al/β-SiC Composites by Mechanical Stirring Casting and High Pressure Die Casting

Aluminium Foam and Magnesium Compound Casting Produced by High-Pressure Die Casting

Nowadays, fuel consumption and carbon dioxide emissions are two of the main focal points in vehicle design, promoting the reduction in the weight of vehicles by using lighter materials. The aim of the work is to evaluate the influence of different aluminium foams and injection parameters in order to obtain compound castings with a compromise between the obtained properties and weight by high-pr...
