Abstract

Изобретение относитс  к металлургии, в частности к способам высокотемпературной термомеханической обработки, и может быть использовано дл  упрочнени  быстрорежущих сталей. Цель изобретени  - повышение прочности и ударной в зкости быстрорежущих сталей. Быстрорежущую сталь нагревают до температуры аустенизации, деформируют при этой температуре со степенью обжати  40-50%, охлаждают до 950-1100°С со скоростью не менее 55°С/с, провод т окончательную деформацию со степенью обжати  25-35% и закаливают. Обработка быстрорежущих сталей по предложенному способу приводит к повышению предела прочности при изгибе и ударной в зкости стали. 1 табл.The invention relates to metallurgy, in particular to methods of high-temperature thermomechanical processing, and can be used to strengthen high-speed steels. The purpose of the invention is to increase the strength and toughness of high-speed steels. High speed steel is heated to austenization temperature, deformed at this temperature with a reduction rate of 40-50%, cooled to 950-1100 ° C at a speed of at least 55 ° C / s, the final deformation is carried out with a reduction rate of 25-35% and quenched. The treatment of high speed steels according to the proposed method leads to an increase in the flexural strength and impact strength of the steel. 1 tab.

Description

Изобретение относитс  к металлургии , в частности к способам высокотемпературной термомеханической обработки , и может быть использовано дл  упрочнени  быстрорежущих сталей.The invention relates to metallurgy, in particular to methods of high-temperature thermomechanical processing, and can be used to strengthen high-speed steels.

Цель изобретени  - повышение прочности и ударной в зкости быстрорежущих сталей.The purpose of the invention is to increase the strength and toughness of high-speed steels.

Способ заключаетс  в следующем.The method is as follows.

Быстрорежущую сталь нагревают до температуры аустенизации, деформируют при этой температуре со степенью обжати  40-50%, охлаждают до 950 -. 1100°С со скоростью не менее , провод т окончательную деформацию со степенью обжати  25-35% и закаливают.High-speed steel is heated to austenization temperature, deformed at this temperature with a degree of reduction of 40-50%, cooled to 950 -. 1100 ° C at a rate of at least, the final deformation is carried out with a degree of reduction of 25-35% and quenched.

Ниже приведены примеры конкретно- : го выполнени  способа.The following are examples of specific: method implementation.

Обработке подвергали пруток диаметром 12 мм из стали РбМ5 с применением радиального обжати  на радиаль- но-ковочной машине SHK-10.A bar with a diameter of 12 mm from steel RbM5 was subjected to treatment with the use of radial compression on the radial forging machine SHK-10.

Режимы обработки и свойства стали представлены в таблице.Processing modes and properties of steel are presented in the table.

Как следует из представленных данных , обработка быстрорежущей стали по предлагаемому способу приводит к повышению предела прочности при изгибе и ударной в зкости стали.As follows from the data presented, the processing of high-speed steel using the proposed method leads to an increase in the flexural strength and impact strength of the steel.
