Some peculiarities of chips oxidation, containing magnesium
Литьë 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

Technological problems of modifying of structure of silumin castings. Solutions
Литьë 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 considerations on the machinability of silumin
Journal of Japan Institute of Light Metals, 1969 As described in the previous report, it was found that silumin has a considerably high cutting resistance which gives fairly great wear of tools; and good cutting finish surface cannot easily be obtained. It was also found that improvement of its machinability was considerably effective by the addition of small amounts of sodium, calcium, etc., but was

INFUENCE OF MODIFIERS ON THE CHANGE OF MECHANICAL PROPERTIES OF SILUMINS
Izvestiya 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.
