Effect of high die angle and strain hardening coefficient on central bursting of carbon steel wires

Effect of high die angle and strain hardening coefficient on central bursting of carbon steel wires

$15.00

This paper is a continuation of work concerned with experimental verification of the Avitzur, Wright, and Yoshida criteria for central bursting in drawing of high-carbon steel wire in dies with semi angles smaller than 10 degrees and single reductions in the range from five to 41 percent. Using the equations of Zimerman and Avitzur, a theory for the effect of strain hardening on central bursting was established in which decreasing the strain hardening coefficient increases the possibility of central bursting under given friction conditions.
