A high-strength alloy with high corrosion resistance and good casting properties has been created at the National University of Science and Technology "MISIS". This was reported by the university's press service.
The composition of the new material includes aluminum, copper, magnesium, zinc, chromium, zirconium and erbium. It is planned to be used in structural engineering at extreme temperatures, in the aerospace and automotive industries.
Combining these ideas allowed us to create an alloy that combines all the most important performance characteristics: corrosion resistance, casting properties and strength, including at high temperatures. New alloys can have a wide range of applications in many industries.
The new alloy has become significantly more resistant to heating and less susceptible to cracking in products during their casting. This was achieved by including erbium and yttrium in the composition of the material.
The developers found that the alloy retains structural stability even at a temperature of 210°. It also tolerates various loads better compared to other analogues.
Earlier www1.ru reported that Rusal has improved the alloy for high-speed trains.
