Effect of boron on the mechanical properties and fine structure of medium-carbon steel

Metal Science and Heat Treatment Aims and scope

Conclusions

Small additions of boron (0.002%) substantially increase the fracture toughness and change the fine structure of the steel investigated. The block size decreases and the dislocation density in subboundaries increases, which changes the overall character of the dislocation arrays.
