Effect of Hot Deformation on Proeutectoid Ferrite Ledge Growth From Boundary of Undercooled Austenite

摘要：

Stored deformation energy of undercooled austenite at 780 ℃ for Fe-0.073％ C steel is in the order of 5 J/mol,corresponding to the dislocation density in the order of 1014 m-2. After deformation at 780 ℃ with 5 J/mol stored deformation energy, proeutectoid ferrite growth rate is accelerated by 2.2％. In this work, the effect of hot deformation below Ae3 on proeutectoid ferrite growth rate is not significant.

关键词： proeutectoid ferrite stored deformation energy ledge
