چکیده مقاله:
The static strain aging behavior of low carbon steel wires after drawing process isstudied. To do so, the wires are austenitized at different temperatures and cooled in different rates.Then the wires are drawn and aged at a specific temperature and time. Before and after aging ofeach drawn wire, the hardness distribution at its cross section is measured. The increase inhardness due to aging is called aging index. The results show that the hardness of drawn wire isincreased from center to surface of its cross section. However, after aging the hardness isdecreased from center to surface. In addition, with increasing the austenitizing temperature, theindex is increased. Also, with increasing the cooling rate, the index is decreased. Moreover, theaging index is decreased from center to surface.
