TOMSK, Dec 25 – RIA Tomsk. Scientists of Tomsk State University (TSU) plan to create a method within two years by means of which it
will be possible to increase conductivity of aluminum wires for power
transmission, the employee of the Laboratory of Manotechnologies in Metallurgy
of the university Ilya Zhukov reported to RIA Tomsk.
"Level of consumption of the electric power
constantly grows, load of the existing power lines (whiche are often not new)
increases because of it. The electric grid companies are forced to transfer
load on wires of bigger section. But they are heavy, old support were not
constructed for them, it is necessary to build new ones", – he told.
According to Zhukov, the development of TSU will increase
durability of light aluminum alloys not less than for 50% without decrease in
conductivity and will help to solve the problem of power engineering
specialists. The method offered by the scientists will increase plasticity for
7-8% and conductivity of metal by 1,5-2%. To improve properties of aluminum,
the scientists enter into melt micro and nanoparticles of metal borides,
influencing with ultrasound for their uniform distribution in alloy.
"Boron is widely applied in metallurgy to purify
metal of foreign impurity and to increase conductivity. However it is
impossible to enter it into aluminum in pure form therefore we will use
boron-containing ligatures. Thanks to external ultrasonic influence evenly
distributed nonmetallic particles will increase mechanical properties of alloys
considerably", – he noted.

The scientist told that boron will promote increase in
conductivity of alloy. Designs of such material will be easier therefore the
power line can be carried out on long distances. Also alloy can be used in the
aviation industry.
The researchers won the Russian President's grant in
1,2 million rubles for the work. Similar class of a ligature isn't made in
Russia; the domestic companies buy them in the Netherlands and Germany.
"We want to exceed foreign alloys on indicators, – Zhukov emphasized. – We
worked in other projects, for example, with the European Space Agency, and
there we managed to exceed indicators".
