Description

Изобретение относитс  к способам обработки высоколегированных сталей, например быстр ор ежу ш.их.The invention relates to methods for treating high-alloy steels, e.g., fast steel hedgehog.

Известен способ высокотемпературной термомеханической обработки быстрорежущей стали, включающий нагрев, аустенизацию, деформацию при температуре стабильности аустенита и охлаждение. Однако снижение температуры деформации при контакте с деформирующим инструментом ухудщает свойства стали.The known method of high-temperature thermomechanical treatment of high-speed steel, including heating, austenization, deformation at austenite stability temperature and cooling. However, a decrease in the temperature of deformation upon contact with a deforming tool deteriorates the properties of the steel.

Дл  повыщени  прочности, пластичности и стабильности свойств сталей по предлагаемому способу деформацию осуществл ют инструментом , нагретым до температуры деформации .In order to increase the strength, ductility and stability of the properties of steels by the proposed method, the deformation is carried out with an instrument heated to the deformation temperature.

Описываемый способ включает нагрев и аустенизацию стали, ее деформацию при температуре стабильности аустенита с помощью инструмента, например щтампа, температура которого поддерживаетс  на уровне оптимальной температуры деформации стали, и охлаждение .The described method includes heating and austenitization of steel, its deformation at austenite stability temperature using a tool, such as a chip, the temperature of which is maintained at the optimum temperature of steel deformation, and cooling.

Описываемый способ высокотемпературной обработки опробован при изготовлении режущего инструмента из быстрорежущей стали Р6М. В результате такой обработки с использованием инструмента, нагретого до температуры деформации, прочность стали возросла на 10-20% с одновременным увеличениемThe described method of high-temperature processing was tested in the manufacture of cutting tools from high-speed steel P6M. As a result of this treatment using a tool heated to the deformation temperature, the strength of the steel increased by 10–20% with a simultaneous increase in
