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

Changes of Material Properties of Silumin During Age-Hardening
Communications, 2012 Simple phenomenological description of age-hardening kinetics of supersaturated solid solution is presented using the sum of exponential functions with negative arguments containing rate constants whose temperature dependence is described by the ...

Double Modification Of AlSi9Mg Alloy With Boron, Titanium And Strontium
Archives of Metallurgy and Materials, 2015 The microstructure of an unmodified AlSi9Mg alloy comprises large primary α phase dendrites, eutectic β phase crystals and eutectic α phase. This composition is responsible for the alloy’s low strength parameters, and it limits the extent of practical ...

Scientific problem of modifying of primary crystals a -phase of silumin castings. Solutions
Литьë и металлургия, 2019 It is shown that intermetallic metals of the modifying ligatures are not the crystallization centers of primary crystals of a a-phase. As the main demodifier serves hydrogen dissolved in liquid silumin.

NANOSTRUCTURIZATION IN FOUNDRY PROCESSES
Литьë и металлургия, 2018 It is shown that at crystallization of alloys the sophisticated nanostructural processes have place. The nanocrystals of phases, their atoms, the centers of crystallization of dendrites, surface-active elements, gases, modifying elements, poorly soluble ...
