The ultrafine-grain steel 10 obtained by equal-channel angular pressing at 200°C is investigated. The structural strength of the steel samples is analyzed, with tensile tests and assessment of the impact strength and crack resistance. The strength of steel increases by a factor of 2.5 after equal-channel angular pressing. In the specified conditions, such treatment does not change the cold-brittleness threshold of steel 10. However, the interval of ductile-brittle transition becomes narrower. Calculations show that the crack resistance K 1C of steel 10 with an ultrafine grain structure is somewhat greater than that of the regular steel. The corrosion rate of uncoated steel 10 samples after equal-channel angular pressing is somewhat greater than in the initial state. However, the corrosion rate of coated steel 10 samples after equal-channel angular pressing is half that in the initial state. The significance of these findings is discussed.
