Abstract
A process for producing ultrafine grains in a steel, comprising employing at least one cycle in which the steel is rapidly heated above its temperature for just enough time to transform it to an austenitic structure, then immediately cooling it at an equal speed or higher than that necessary to transform austenite into a fine-grained ferrite perlite aggregate, characterized in that said steel is previously treated by preheating it to a temperature of the order of (A1-83.3)ºC to a temperature immediately below the A1 temperature of steel, for a period of from about 5 minutes to about 30 minutes before each of the rapid heat cycles used.
