| Abstract: | The role of aluminum alloying on strength properties and deformation mechanisms (slip, twinning) of 〈123〉 single crystals
of Hadfield steel under tensile loading at T = 300 K is demonstrated. It is found out that aluminum alloying suppresses twinning
deformation in the 〈123〉 single crystals and, during slip, results in a dislocation structure change from a uniform dislocation
distribution to a planar dislocation structure.
