Dislocation structure of martensitic transformation in carbon steel

Resumo

The developed method of diffraction analysis has shown that the martensitic transformation in iron crystals with the interstitial carbon atoms produces the highest natural density of dislocations in metals. The transformation occurs via microscopic shears, which collectively rearrange the lattice. This process becomes more evident due to the high concentration of fine dislocation loops, which has initially been identified in cubic and then in tetragonal martensite crystals.
