Abstract

This paper presents the study of multiphase lightweight boron carbide based composites manufacturing and recycling features via powder metallurgy technology. The manufacturing process includes self-propagating high-temperature synthesis (SHS) followed by a hot densification at liquid-state of aluminum binder phase. For composite properties optimization the heat treatment in vacuum at different conditions was used. Additional heat treatment in oxidizing environment was used for spontaneous disintegration and recycling of the investigated material.
