Abstract
It was set the influence of the duration of irradiation of the melt by nanosecond electromagnetic impulses (NEMI) and subsequent silicon modification on the crystallization and structure formation processes, physical-mechanical and operation properties of gray cast iron. The cause of eutectic displacement of gray cast iron depending on the silicon composition when exposed to the melt NEMI was determined. It was proved by the method of X-ray spectrum analysis on the installation “Jolie 8600” (Japan) that under irradiation of the melt by NEMI the solubility of manganese is increased but silicon and carbon content in excess austenite is reduced sharply. Therefore, the melt is enriched with carbon and silicon, thus facilitat- ing the obtaining of eutectic melt composition.
Highlights
Чугун состава 3,3 % С; 1,5 % Si; 0,7 % Mn; < 0,1 % P и S перегревали до 1550 °С и выдерживали при этой температуре в течение 5 мин

Summary
Чугун состава 3,3 % С; 1,5 % Si; 0,7 % Mn; < 0,1 % P и S перегревали до 1550 °С и выдерживали при этой температуре в течение 5 мин. Например, в чугуне, модифицированном 1,0 % ФС 45, эвтектическая концентрация углерода достигается при облучении расплава НЭМИ в течение 20 мин. Чем больше содержание кремния в исходном чугуне, тем меньшей продолжительностью облучения расплава достигается эвтектическая концентрация углерода.
