Researchers from the National University of Science and Technology "MISiS" (NUST MISIS) together with fellow Russian scientists have created an inexpensive aluminium alloy that can withstand temperatures 100-150C higher than its analogues.
The scientists responsible for the creation claim that the material would significantly reduce the weight and carbon footprint of new rail vehicles, aircraft and other machinery. Their study has been published in the Journal of Alloys and Compounds.
Aluminium and most aluminium-based alloys are highly resistant to corrosion in almost all environments: the atmosphere, seawater, freshwater, many chemical solutions and most foodstuffs. Given these properties, as well as its low specific gravity and good thermal and electrical conductivity, aluminium is widely used in aircraft, automotive, electronics and other industries.
Aluminium alloy wire could be an effective substitute for the expensive and heavy copper-based conductors used today, the scientists said. Its use in aircraft, high-speed rail vehicles and other equipment would reduce their weight and size characteristics, thereby ensuring significant fuel savings and reducing harmful emissions into the atmosphere. However, the methods of producing such alloys and their element base are extremely expensive and labour-intensive today, NUST MISIS reported.
University specialists have proposed the structure of a new aluminium-based alloy, as well as the technology to produce wire from it....
