AlSi casting alloys combine excellent castability with high strength. Hence, this group of is often used in the automotive sector. The challenge for application brittle character these which leads to cracks during joint formation when mechanical joining technologies are used. A rise ductility can be achieved by a considerable increase solidification rate results grain refinement. High rates rea...

Aluminium murni memiliki castability yang baik tetapi sifat mekaniknya tidak baik. Oleh karena itu, untuk meningkatkan mekaniknya, ditambahkan elemen paduan lain seperti magnesium, tembaga, mangan, silika dan beberapa. Penelitian ini dilakukan mengetahui pengaruh temperatur tekanan tuang terhadap nilai kekerasan material pengecoran logam. Bahan menggunakan aluminium-tembaga (Al-6,7%Cu). Metode ...

Eutectic high entropy alloys are gaining increasing attention due to their excellent castability and combination of strength ductility in the as-cast state. However, detailed behavior nano-scale lamellar microstructure during deformation, particular interaction between phases, is not well understood. Here we use in-situ neutron diffraction tensile testing over a wide temperature range (77–673 K...

The objective of the present work is to study the casting characteristics of various A1-Li alloys, which include fluidity and strengths of the alloys and their interaction with cast molds. Materials investigated are Al-Li-Mg and Al-Li-Cu-Mg alloys with Li content of 2.5 wt%. The results show that sand molds with resin binders are good for A1-Li casting. Ceramic coatings can further reduce the m...

This paper aims to design lattice structures for rapid-investment casting (RIC), and the goal of methodology is minimize defects that are related topology. RIC can take full advantage unprecedented freedom provided by AM. Since has multiple objectives, we limit our study already have good printability, i.e., self-supported open-celled, improve their castability. To find relationship between top...
