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.

Astrophysical Constraints on Modifying Gravity at Large Distances [PDF]

open access: yes, 2001
Recently, several interesting proposals were made modifying the law of gravity on large scales, within a sensible relativistic formulation. This allows a precise formulation of the idea that such a modification might account for galaxy rotation curves ...
