Modeling pearlite transformation in super-high strength wire rods: II. Simulation in Fe-C base multi-component alloys

Abstract

A model of pearlite transformation developed in a companion paper was applied to the transformation in experimental multi-component super-high strength wire rods, which contained Si, Cr, Mn, V and Ti. It was assumed that the transformation occurred without partitioning of alloying elements below the nose temperature where patenting is usually performed. Calculated pearlite start and finish temperatures and lamellar spacing were in good agreement with experiment by Gleeble thermomechanical simulator. The importance of controlling recalescence was noted in order to make lamellar spacing as small as possible. © 2012 ISIJ.
