(RDMag) A team from the National University of Science and Technology MISiS may have found a way to double the strength of composites obtained by 3D printing from aluminum powder. To strengthen aluminum researchers have developed a new composite that maintains it is lightweight while significantly improving its strength. The did this by developing new modifying-precursors for 3D printing based on nitrides and aluminum oxides that were obtained through combustion.
“We have developed a technology to strengthen the aluminum-matrix composites obtained by 3D printing, and we have obtained innovative precursor-modifiers by burning aluminum powders,” Alexander Gromov, head of the research group, said in a statement. “Combustion products – nitrides and aluminum oxides – are specifically prepared for sintering branched surfaces with transition nanolayers formed between the particles.
