Abstract

Analysis of dislocation substructures evolution in austenite steels 08H18N10T (0.1 wt.% C, 18 % Cr, 9 % Ni, 1 % Ti), 45G17Yu3 (0.45 wt. % C, 17 % Mn, 3 % Al) during low-cycle and multicycle fatigue tests before failure was performed by transmission electron microscopy methods. Quantity dependences of dislocation scalar density changes, lattice curvature-torsion amplitude upon load cycles numbers were determined. It allowed to analyze the dislocation substructure transformation chains, and to determine the steel fatigue failure sources.
