Iranian Researchers Make Amorphous Alloy Nanoparticles to Compete with Stainless Steel
This research was carried out by Alireza Mohammadian, a Ph.D. student of the Department of Physics, Faculty of Sciences of Chamran University, under the title of ‘manufacturing and characterization of aluminum-based amorphous alloy nanoparticles Al1-x-yMx (M= Fe, Co) Cry by electric arc method and investigating their magnetic, electrical and corrosion properties’.
Mansour Farbod, the supervisor of the thesis, elaborated on the research, saying, “Amorphous alloy nanoparticles Al1-x-yMx (M= Fe, Co) Cry, which were produced for the first time by using the electric arc method in the physics department of Shahid Chamran University of Ahvaz, are ferromagnetic, low-price, light, hard and corrosion resistant.”
He added that the alloys enjoy these special specifications due to the amorphization of the crystalline network in the nano scale, noting that it is about four times harder and 140 times corrosion resistant more than the L316 steel, and it is a widely used alloy in the field of petroleum, specially the petrochemical industries.
Alireza Mohammadian, the researcher, also said that aluminum, iron, cobalt and chromium were used in making the amorphous alloy nanoparticles, adding that it increases the lightness, corrosion and hardness of the alloy and many industrial applications are predicted for it in the future.
“The produced amorphous alloy is capable of competing with L316 stainless steel, which is an alloy used in the steel industry, and its lightness and lower price compared to steel are among the other advantages of this product.
The results of this research, which has been conducted in the form of a thesis, were published in the prestigious Journal of Alloys and Compounds.
Iran has considerably made progress in nanotechnology and increased its exports of nanotechnology products and many countries are currently importing such goods.
"The volume of Iran’s nanotechnology export is eye-catching and the country is exporting its nano products to 21 countries,” Director of Industrial Promotion Group of Iran's Nanotechnology Development Department Ali Tahari said.
"After putting into operation the nano-fabric industrial production line, we were able to export this technology to South Korea and we signed a contract to export it to China as well," he added.
Iran has already announced that the country exports its nano products to countries like Australia, China, South Korea, Malaysia, Turkey, Russia and other European countries.
