Influence of aluminum content on the structure of high strength and non-alloyed steel wires used in electronic nanotechnology components

The first ingredient necessary to build molecular-scale circuits is wire. These wires must be very thin, long, strong mechanical and electrical conductance have a good. The work analyze the austenite grain increase tendency, during the heating of high - carbon steels, at 900°C and 1000°C, which represents the limits of austeniting range in order to be patenting. When the carbon content is between 0.65 – 0.80 %, manganese is limited at 0.6 %, appeared that the steel has a small tendency of increasing the grain sizes (in the 900 – 1000°C range), and the aluminum microalloing is no more needed. Producing of steel using heat treatment an aluminum deoxidizing lead to a high purity steel and a fine grain structure after patenting characterized by a high ductility.
