Effect of the Type of Crystal Lattice of Metals on Structure Formation and Mechanical Properties Under Plastic Shear Deformation

The structural state and the post-deformation mechanical properties of steel 10 (bcc), copper M1 (fcc) and titanium Grade 4 (hcp) are studied using the method of free torsion of cylindrical billets below the temperature of recrystallization. The metal acquires a gradual strain distribution with maxi...

Description
Summary:The structural state and the post-deformation mechanical properties of steel 10 (bcc), copper M1 (fcc) and titanium Grade 4 (hcp) are studied using the method of free torsion of cylindrical billets below the temperature of recrystallization. The metal acquires a gradual strain distribution with maximum strain in the surface layer, which provides intense grain refinement and hardening. The refinement is more intense in the bcc and fcc lattices forming a developed substructure by the dislocation mechanism, whereas the hcp lattice reacts primarily by twinning. The strength of the deformed metal with gradient structure is 8 – 17% higher than in the initial condition.
