Abstract
Способ термоциклической обработки инструментальной стали, включающий многократный нагрев выше Ас, охлаждение в цикле ниже Ас, охлаждение в воде или в масле после нагрева в последнем цикле с последующим отпуском, отличающийся тем, что многократный нагрев осуществляют выше Асна 40 - 80С со скоростью 250 - 350С/мин, а охлаждение в цикле приводят в расплаве солей до температуры 560 - 620C с выдержкой при этой температуре до окончания превращения γ _→ α и отпуск осуществляют при температуре 180 - 220С.A method for thermocyclic processing of tool steel, including multiple heating above Ac, cooling in a cycle below Ac, cooling in water or oil after heating in the last cycle, followed by tempering, characterized in that multiple heating is performed above Asna 40 - 80C at a speed of 250 - 350C / min, and cooling in the cycle is carried out in a molten salt to a temperature of 560 - 620C with holding at this temperature until the transformation γ _ → α is completed and tempering is carried out at a temperature of 180 - 220C.
