MODIFYING OF SECONDARY ALLOYS [PDF]

open access: yesЛитьë и металлургия, 2015
It is shown that impurity modifying of secondary alloys inefficiently because of the high contents in fusion of high-disperse nonmetallic particles. They promote receiving not modified microstructure and pollution of castings by nonmetallic inclusions ...

INCREASE OF THE MODIFYING EFFICIENCY [PDF]

open access: yesЛитьë и металлургия, 2006
Short review and analysis of the basic nine well known ways of the metals and alloys modifying are given. It is shown that casting by means of mixing of one- and two-phase melts, casting by quenching hardening, casting in crystallyzer with jet cooling is

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.

Scientific problem of modifying of primary crystals a -phase of silumin castings. Solutions

open access: yesЛитьë 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.
