Description
To verify the effect of cementite thickness, i.e., the effect of transformation temperatures from austenite to pearlite, on void formation at large drawing strain in pearlitic steel wires, the changes in microstructure and mechanical properties with drawing strain were investigated. The results showed that globular cementites were formed in colonies aligned transversely to the drawing direction at high strains, and that the voids were formed at globular cementites during wiredrawing. The high transformation temperatures induce large globular cementites during drawing due to initial microstructure of thick cementite.
