Conclusions 1. The structure and properties of steel with a ferrite-pearlite structure depend on the arrangement of carbide platelets in the ferrite matrix. With an oriented arrangement of cementite platelets the strength increases by 15–20 kg/mm2. The first term in Eq. (2) has the same value — $$\bar \sigma _C v_C \theta \sim 12 kg/mm^2$$ — which is ∼15% of the ultimate strength of the steel with oriented cementite particles. 2. The strength of the composite before and after cold deformation is determined by the strength, size, quantity, and orientation of carbide platelets, the distance between platelets, the amount of free ferrite and the size of its subgrains, and the fine structure of ferrite in pearlite.
