Effect of Al5TiB Master Alloy with P on Microstructure and Mechanical Properties of AlSi7Mg Alloy

open access: yesMetals, 2023
Aluminum-silicon alloys are popular casting alloys. In its raw state, the microstructure of the hypoeutectic silumin consists of a large eutectic β phase against the background of dendritic eutectic α.

Technological problems of modifying of structure of silumin castings. Solutions

open access: yesЛитьë и металлургия, 2019
It is shown that the main technological problems of modifying of structure of silumin castings are: absence of the universal modifiers, limitation of their action in time; saturation of a melt by hydrogen and oxide of silicon.

Some peculiarities of chips oxidation, containing magnesium

open access: yesЛитьë и металлургия, 2002
The process of oxidation of aluminium and silumin shavings has been investigated. It has been stated that presence of magnesium in silumin intencifies oxidation independently on furnace atmosphere composition. The technology of silumin shavings remelting

INFUENCE OF MODIFIERS ON THE CHANGE OF MECHANICAL PROPERTIES OF SILUMINS

open access: yesIzvestiya Vuzov Tsvetnaya Metallurgiya (Proceedings of Higher Schools Nonferrous Metallurgy, 2017
An increase in the sum of alloying elements in industrial silumins causes the formation of excess intermetallic phases in their structure. When introducing modifiers in such alloys above a certain amount, structural components are coarsened because of overmodification, which can cause a decrease in the mechanical properties of cast alloys.
