Mechanical properties of nanocrystalline Ni-20%Fe alloy at temperatures from 300 to 4.2 K
چکیده انگلیسی

Mechanical properties of the nanocrystalline Ni-20%Fe alloy (the average grain size is 22 nm) have been studied under uniaxial compression at different strain rates (from 10−5 s−1 to 10−1 s−1) and temperatures from 300 to 4.2 K. Comparison of the strength characteristics, strain and failure peculiarities of the nanocrystalline and coarse-grained structural states of Ni-20%Fe alloys is carried out. Micromechanisms of plastic deformation in this nanocrystalline alloy (including increase of the slip localization at low temperatures) are discussed.
