Metallographic study on eutectic silumin

AIP Conference Proceedings, 2017
The elemental and phase composition, the state of the defective substructure of eutectic silumin used for engineering were studied by the methods of scanning and transmission electron microscopy. The findings of the study show that silumin is a multiphase material and comprises, along with phases based on solid solutions of aluminum and silicon ...

Hardening of Silumins by Aerothermoacoustic Treatment

Russian Metallurgy (Metally), 2018
The influence of aerothermoacoustic treatment on the formation of the microstructure and the mechanical properties of cast aluminum alloys (silumins) is considered. The experimental data demonstrate that this treatment, which is included in the technological cycle of standard heat treatment or partly replacing it, increases the strength of the alloys ...

Structure and mechanical properties of Silumin

Metal Science and Heat Treatment, 1976
1. The reason for the low plasticity, and in some cases the hardness, of Silumins is the brittleness of silicon particles of lamellar form. These platelets break by splitting even with small plastic deformation of the α matrix. Because of the substantial volume of these silicon particles in the structure of the alloy they have a large effect on ...
