We investigate the kinetics of the structural deformation and hardening of single-crystalline austenitic Fe–13Mn–1.3C (Hadfield steel), Fe–13Mn–2.7Al–1.3C, and Fe–28Mn–2.7Al–1.3C (in wt%) steels with different stacking-fault energies

In this paper, we investigate the microstructure and microhardness of high-nitrogen austenitic steel after high-pressure upset and high-pressure torsion (6 GPa) at room temperature. As the result of deformation, steel microhardness increases by 1.5 t

Mechanisms of structure fragmentation and strengthening of single crystals of a Hadfield steel after warm torsion under high-pressure torsion (HPT) and subsequent annealing in a temperature range of 400–800°C have been studied. Multiple twinning a

Using the method of equal-channel angular pressing (ECAP), submicrocrystalline structure is formed in lowcarbon Fe–Mn–V–Ti–C steel with the average grain size 260 nm in the ferrite-perlite state and 310 nm in the martensitic state. It is esta

The role of mechanical twinning on the fragmentation and the contribution to strengthening was studied using single crystals of Hadfield steel after high-pressure torsion and rolling at room temperature. Multiple twinning was found to be the basic de
