The mechanism of the modification of silumin

Metal Science and Heat Treatment, 1970
1. The modifying effect of calcium is due to its deactivating influence on impurity particles that serve as solidification centers for eutectic silicon in unmodified Silumin. 2. Along with its possible influence on deactivation of impurities, the modifying effect of sodium is due to its reduction of the solidification rate of the ...

Characteristic features of silumin alloys crystallization

Materials & Design, 1997
Abstract The results differential thermal analysis (DTA) of crystallization of multicomponent silumin alloys with 8÷22 wt %Si and Mg, Cu, Ni and Fe minor admixtures are presented in the paper. It has been proved that to any one of the solid phases crystallizing from liquid (α, β, Mg 2 Si, Al 6 Cu 3 Ni, Al 2 Cu, Al g Fe 2 Si) a particular thermal ...

EFFECT OF REE ON THE SOLIDIFICATION OF НYPEREUTECTIC SILUMIN

Metally, 2023
The theories and mechanisms explaining the processes of primary silicon modification in hypereutectic silumins are considered. The processes of crystallization of hypereutectic silumin treated with rare-earth elements (REE): yttrium, ytterbium, samarium, erbium, lanthanum and neodymium have been studied.

Silumins: The Automotive Alloys

AM&P Technical Articles, 2012
Abstract Aluminum-silicon (Al-Si) alloys have good castability in combination with high corrosion resistance, thermal conductivity, and specific strength, making them a strong candidate for many automotive applications. This article describes the processes used in the production of die-cast AlSi9Mg engine brackets for Volvo trucks, the ...

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 ...

Fractographic features of the fracture of silumins

Metal Science and Heat Treatment, 1981
1. Fracture of silumins in static loading starts with the formation of voids around the silicon particles. The size of the voids is comparable with the size of of the particles, which is responsible for the close relationship of the fracture relief to the degree of dispersion of the structure. 2.

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 ...
