It is worth noting that aluminum and its alloys takes the second place in terms of scale after steel. This metal has a number of advantages, such as: lightness, corrosion resistance, strength, ductility, etc.
The use of sheet superplastic molding (SPF) allows to obtain integral parts of complex design from aluminum alloys. However, given the fact that most materials used for SPF are characterized by a low deformation rate and elongation of up to 300%, quite a lot of time is spent on the manufacture of the final part. This ultimately affects its value, 70-80% of which falls on technological process.
Scientists from NITU MiSiS managed to get the type of aluminum alloy, which is 20-30% stronger than analogues, and its allowable degree of deformation exceeds 400%. At the same time, it will take only 15-20 minutes to manufacture a part from this material by SPF, which significantly reduces the process and the final cost of the product.
According to the assistant professor of NITU MISiS, Anastasia Mikhailovskaya, due to the properties of the new alloy, it will be possible to manufacture parts of complex shape on equipment of relatively low power.
In the near future, scientists will begin testing a promising material in the production of sheets and will get an international license. Then, the alloy can be introduced into production.
