Description

щественно улучшает технологичность ввода, преп тствует образованию ликвационных дефектов и уменьшает окисление алюмини .significantly improves the processability of the input, prevents the formation of segregation defects and reduces the oxidation of aluminum.

Описываемый способ обеспечивает когерентное распределение легирующих элементов в структурных составл ющих чугуна, что обусловливаетс  одновременностью процессов плавлени  и диффузионного растворени . Применение данного способа получени  чугунных отливок, содержащих 0,1-0,5% алюмини  и 0,5-4,0% меди, позвол ет повысить механические свойства чугуна в среднем на 15-25% по сравнению с известными способами .The described method provides a coherent distribution of alloying elements in the structural components of cast iron, which is caused by the simultaneous melting and diffusion processes. The use of this method for producing iron castings containing 0.1-0.5% aluminum and 0.5-4.0% copper allows an increase in the mechanical properties of the iron, on average, by 15-25% compared to known methods.
