Abstract:
The effect of tempforming temperature on the microstructure and mechanical properties, especially impact toughness, of the S700MC-type high-strength low-carbon steel was investigated. Tempforming at temperatures of 923 and 973 K was characterized by the development of ultrafine-grained layered microstructure consisting of grains highly elongated in the rolling direction with the transverse grain size of 530 and 920 nm, respectively.
