| Abstract |
Spheroidization of cementite in eutectoid steel by concurrent warm torsional deformation has been studied with emphasis of the effects of the strain rate and the inter-lamellar spacing. Complete spheroidization could be achieved in 3 minutes when the strain rate and the deformation temperature were 1.76 percent/sec 700℃ respectively. The rate of the sphsroidization increased with increasing temperature at a given strain rate and lameller spacing. The coarse pearlite was more easily spheroidizad than the fine pearlite when other conditions were same. |
