ALUMINUM-BASED COMPOSITE MATERIAL (VERSIONS) AND ARTICLE MADE THEREFROM Russian patent published in 2019 - IPC G21F1/08 C22C1/10 C22C21/00 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to materials for protection against radiation, having high heat conductivity, heat resistance to 400 °C and low value of thermal expansion coefficient, and can be used in nuclear, radiochemical industry, as well as in naval and aerospace industry in order to protect service personnel and the environment. Composite material based on aluminum consists of boron carbide with content of 40–60 wt. and silicon carbide from 5 to 25 wt%, rest is matrix from aluminum or foundry aluminum alloy of Al-Si system, as well as article made from it. Composite material based on aluminum consists of boron carbide with content of 30 to 59 wt%, boron isotope 10 with content from 1 to 10 wt. and silicon carbide from 5 to 25 wt%, rest is matrix from aluminum or foundry aluminum alloy of Al-Si system, as well as article made from it.

EFFECT: invention increases heat conductivity and protection against radiation.
