Mathematical Model of Relation between Microstructure and the Yield Strength of High Carbon Steel Wire Rods

Abstract:

Ferrite content and the plate distance of pearlite of high carbon steel wire rod are analyzed by Optical Microscope and SEM, using quantitative microstructure analysis technology. The relation between microstructure and yield strength of high carbon steel wire rods was investigated. And the mathematical model of the relation was established as: σs(Pa)=104.52×106+161.70(1－fα 1/3)S－1(m). It was validated by experiment data that the mathematical model agrees well with the experimental results.
