the flow stress of steel depends significantly on microstructural changes taken place during hot deformation processes. in hot deformation processes, the flow stress of steel is influenced by two main metallurgical phenomena, i.e. recovery and recrystallization, along with its chemical composition and thermo-mechanical parameters. the final mechanical properties of steel are also determined by ...

Abstract Hot stamping is a commonly used procedure to manufacture components from high strength steels, which are for parts of car bodies. Against the background production efficiency and costs, there number factors determine performance tools in hot stamping, e.g. cycle time lifetime tools. Main requirement wear resistance, while additional properties such as thermal conductivity can be consid...

This work considers use neurofuzzy set theory for estimate abrasion wear resistance of steels based on chemical composition, heat treatment (austenitising temperature, quenchant and tempering temperature), hardness after hardening and different tempering temperature and volume loss of materials according to ASTM G 65-94. Testing of volume loss for the following group of materials as fuzzy data ...

Temperature is the main process variable needed for every operation in hot rolling process for all value addition activity and can be considered as main variable also to control pollution.. It is a tool for the steel hot rolling plant to improve profitability, environment and productivity by controlling the process energy balance by its sequences optimization. In the steel rolling plant the imp...
