Description

Results of an investigation into the effects of low temperature aging on the mechanical properties and microstructure of high carbon steel wire, and a mathematical model of wiredrawing, are presented. Strain aging behavior in pearlite is strongly microstructure dependent and fine pearlite drawn to high strains is more susceptible to strain aging. Strain aging can be nearly be eliminated using direct water cooling if the drawing speed is high enough and if a suitable method for post-drawing cooling is used.
