Strain Aging of Heavily Drawn Pearlitic Steel Wires

Article Preview

Abstract:

The strain aging of heavily drawn pearlitic steel wires has been studied by means of electrical resistivity mearsurement. The kinetic of the early stage of strain aging after being drawn to true strain 2.89 is described by a Johnson-Mehl equation. The apparent activation energy ΔH is estimated as 31.7kJ/mol. The results indicate that the mechanism of the early stage of strain aging of heavily drawn pearlitic steel correlates with the formation of interstitial solute atoms-vacancy pairs.
