Stability mechanism of AlSi12 aluminum foam under the action of Al–Si–Ca second phase
Journal of Materials Research and Technology, 2021 AlCa75 with equal Ca content was used to replace pure Ca for the preparation of AlSi12 foam in a stable pore structure after foaming for 20 min. The stability mechanism was studied based on the comparison between the macroscopic pore structure evolution ...

Steel Ball Impact on SiC/AlSi12 Interpenetrated Composite by Peridynamics. [PDF]
Materials (Basel)Silicon carbide and an aluminum alloy (SiC/AlSi12) composite are obtained during the pressurized casting process of the aluminum alloy into the SiC foam. The foam acts as a high-stiffness skeleton that strengthens the aluminum alloy matrix. The goal of the paper is to describe the behavior of the material, considering its internal structure.

Influence of Powder Characteristics on Processability of AlSi12 Alloy Fabricated by Selective Laser Melting. [PDF]
Materials (Basel), 2018 Selective laser melting (SLM) is one of the additive manufacturing technologies that allows for the production of parts with complex shapes from either powder feedstock or from wires. Aluminum alloys have a great potential for use in SLM especially in automotive and aerospace fields.
