| Abstract: | The features of martensitic transformations upon the low-temperature (1.8–300 K) deformation of metastable Fe-18Cr-10Ni and Fe-18Cr-15Ni alloy single crystals with low stacking-fault energies were studied. It was shown that the γ → ɛ and γ → α martensitic transformations play the main role in increasing strength and plasticity when the deformation temperature is reduced to 4.2 K. |
