| An effect of loading during uniaxial tension at different rates ranging from 10-4 to 10-2 s-1 on the phase transformation "austenite-martensite" in the surface layer of hardened 0.36%C-14%Ni steel type with an unbalanced (α+γ)-structure has been determined by an X-ray structure analysis. The mechanisms of (γ-α)-transformation through the depth of steel surface layer and character of this transformation propagation along the specimen length depending on external stress value and tension rate have been defined. |
