摘要：

The increased interlamellar spacing causes the larger sized globular cementite particles in colonies initially aligned transverse to the drawing axis, and results in the occurrence of more frequent and larger sized void formation during drawing. The array of those voids would act as one of the origins for delamination or offer the preferential site for delamination during torsion. Thus, the occurrence of delamination in coarse pearlite is much easier than in fine pearlite.
