Abstract

Способ термической обработки сталей с многократной быстрой закалкой и низким отпуском, включающий непрерывную закалку и последующий низкий отпуск, отличающийся тем, что между непрерывной закалкой и низким отпуском производится серия повторных закалок с высокой скоростью нагрева до температуры аустенизации и малым временем выдержки при температуре аустенизации.A method of heat treatment of steels with multiple quick hardening and low tempering, including continuous hardening and subsequent low tempering, characterized in that between continuous hardening and low tempering a series of repeated hardening is performed with a high heating rate to the austenitizing temperature and a short exposure time at the austenitizing temperature.
