Influence of the Structural Parameters of High-Carbon Steel on the Impact Strength

Steel in Translation Aims and scope

Abstract

For a coil of rolled C86D steel subjected to accelerated continuous cooling from the hot-deformation temperatures, change in austenite grain size by scores no greater than 1–2 according to State Standard GOST 5639–82 has no significant influence on the impact strength. For C86D steel, the impact strength is directly related to the extent of the ferrite–cementite phase boundaries: the impact strength increases with increase in the boundary length. These results are of practical interest in developing new alloys and conditions of deformation and heat treatment for high-strength pearlitic steels.
