Abstract
The production technology development of surface fine grain steel by CRCT(TMR) is performed in order to improve the strength and toughness of Dowel Bar without additional treatment. It is possible to obtain surface ultra fine grain steel, when warm deformation of martensite formed after on-line quenching is carried out from 650℃ to 780℃ in the finishing rolling step. The characters of surface with ultra fine grain steel is showing the cementite particles inside the ferrite grain and fine ferrite grain of about 1.2 ㎛ in size. It is also confirmed that the Gleeble simulation of this production technology make ultra fine grain structures at similar temperature range from 740℃ to 800℃.
