Article

The effect of austenitizing temperature (880 – 1000°C) on the incubation period and bainitic transformation in steel 0.88% C – 1.35% Si – 1.0% Cr – 0.43% Mn is studied by the methods of x-ray diffraction and optical and transmission electron microscopy. The effect of the austenitizing temperature on the temperature and incubation period of the nose of the C-curve of the bainitic transformation is determined. The influence of a 20-min hold at 250°C after the austenitizing on the bainitic structure is studied.
