In this study, the effect of pearlite microstructure on mechanical properties has been analyzed.The high carbon steel wire rods were treated by traditional salt-bath isothermal heat treatment and a new process, respectively. The microstructures and mechanical properties of the wire rods were tested with SEM and Instron 8501. The results shown that with the decrease of the isothermal holding temperature, the pearlite interlamellar spacing and pearlite colony size decreased and the mechanical properties of the wire rod increased. Especially the interlamellar spacing and pearlite colony size were decreased by new heat treatment observably. With the new treatment, the reductions of area increase.

In order to enhance the strength of cold drawn high carbon steel and improve its comprehensive properties ,the law of change in microstructures and properties of high carbon steel with various contents of V and N were investigated .The size of pearlite colony，interlamellar spacing of pearlite and mechanical properties with various contents of V and N were measured; the change of magnetic properties of wires with different cold drawing strains were measured by VSM. It is shown that V can decrease the size of pearlite colony and interlamellar spacing of pearlite when V content is less than 0.06 wt %; N can decrease the size of pearlite colony and increase slightly the interlamellar spacing of pearlite. The tensile strength is enhanced with increasing V or N content, but V decrease plasticity of wire and N has little effect on it. The cementite in wire is dissolved with increasing cold drawing strain. The volume fraction of cementite is decreased to 4.4%，dissolution of 7.8%，as the true strain is increased up to 3.19.

Weld Heat

The high-carbon steel strips are one of the most widely used base materials of bandsaw blade manufacturing. These materials have sufficient strength and ductility to cope with the high fatigue load of the bandsaw blades. These endless strips are produced by welding, and therefore the weld and the heat affected zone have different mechanical properties, like tensile strength and fatigue resistance, than the base material. These properties of the weld can be influenced by preheat and post weld heat treatment. Regarding to the latest industrial requirements, the application of laserbeam welding was examined to produce higher standard bandsaw blade. The laserbeam welded joints has lower heat input and narrower heat affected zone compared to metal inert gas (MIG) welding, which is currently used in bandsaw blade manufacturing. To assure the proper mechanical properties and sufficient resistance to fatigue, an examination was carried out to determine the effect of preheat temperature and post weld heat treatment time on the mechanical properties and fatigue behaviour of the laserbeam welded joint.

Lamellar Pearlite

The main characteristics of metal long products quality include mechanical properties, depending on the microstructure state. The key indicator for evaluation the micro-structure of high carbon steel can be considered the 1st grain grade lamellar pearlite Bfp. For the currently used pearlite dispersion method, according to GOST 8233-56, it is characterized by the subjectivity of the view fields choice for the microstructure evaluation, that reduces the quality of the obtained results. The study purpose was to improve the method of high-carbon steel wire rod microstructure estimation, to reduce the error magnitude in determining the 1st grain grade lamellar pearlite. The experiments were carried out on samples of high-carbon steel wire rod with a carbon content of 0,58 – 0,77 %. The pearlite dispersion was evaluated in 27 view fields, located on mutually perpendicular diagonals of the sample cross section. The study results showed the possibility of reducing the error in determining the estimated value of the high-carbon steel wire rod microstructure pearlite dispersion. Microstructure evaluation in the five view fields should be carried out, taking into account the weight coefficients, determined by the ratio of the zones length, occupied by pearlite with a certain percentage of the 1st grade grain pearlite to the wire rod radius. The proposed method of the microstructure evaluation increases assessment accuracy, without complication of its implementation process.
