Abstract
1. Способ термоциклической обработки литых деталей из низколегированных и углеродистых сталей, включающий высокотемпературную аустенитизацию, многократные нагревы и охлаждения со скоростью, обеспечивающей перлитное, или сорбитное, или бейнитное, или мартенситное превращение до температуры на 50-100°C ниже A, или Б, или Ми окончательного охлаждения на воздухе или в закалочной жидкости и ступенчатый высокотемпературный отпуск, отличающийся тем, что высокотемпературную аустенитизацию проводят при температуре на 100-150°C выше точки А, с выдержкой 2,5-3,0 мин на 1 мм сечения детали, а многократные нагревы и охлаждения ведут в межкритическом интервале.2. Способ по п. 1, отличающийся тем, что количество циклов нагревов и охлаждений в межкритическом интервале составляет не менее 3.3. Способ по п. 2, отличающийся тем, что ступень высокотемпературного отпуска выбирается при температуре 400°C, с выдержкой 1,5-2 ч.1. A method for thermocyclic treatment of cast parts from low alloy and carbon steels, including high-temperature austenitization, multiple heating and cooling at a rate that ensures pearlite, or sorbitol, or bainitic, or martensitic transformation to a temperature of 50-100 ° C below A, or B, or Mi final cooling in air or in quenching liquid and stepwise high-temperature tempering, characterized in that high-temperature austenitization is carried out at a temperature of 100-150 ° C above point A, with exposure oh 2.5-3.0 min per 1 mm of the section of the part, and multiple heating and cooling are carried out in the intercritical interval. 2. The method according to claim 1, characterized in that the number of heating and cooling cycles in the intercritical interval is at least 3.3. The method according to p. 2, characterized in that the stage of high-temperature tempering is selected at a temperature of 400 ° C, with a shutter speed of 1.5-2 hours
