Aluminum on the way to titanium strength
NUST MISIS scientists have proposed a technology that can double the strength of composites obtained by 3-D printing from aluminum powder, and advance the characteristics of these products to the quality of titanium alloys: titanium’s strength is about six times higher than that of aluminum, but the density of titanium is 1.7 times higher.
The developed modifiers for 3-D printing can be used in products for the aerospace industry.
The developed modifying-precursors, based on nitrides and aluminum oxides and obtained through combustion, have become the basis of the new composite. The research results have been published in the highly rated scientific journal Sustainable Materials and Technologies.
Two decades ago, molding was considered the only cost-effective way to manufacture bulk products. Today, 3-D printers for metal are a worthy competitor to metallurgical methods. 3-D printers have a chance to replace traditional methods of metallurgical production in the future. Using additive technologies with 3-D printing creates a whole array of advantages, from creating more difficult forms and designs to the technology’s cheaper cost and theoretical edge.
