Description

Сти, теплостойкости, износостойкости, режущих свойств и др.). Например, быст|рорежущие стали Р18, Р12, Р9К5 уже обработапные по предлагаемому способу, имеют нормальную теплостойкость, нормальную или на 1-2 единицы HRC более высокую твердость , на 20-30% более высокую прочность и ударную в зкость, высокую дисперсность зерна (пор дка 12 баллов) и карбитов, повышение режущей стойкости в 1,3-2 раза.Style, heat resistance, wear resistance, cutting properties, etc.). For example, fast-cutting steels P18, P12, R9K5 already processed by the proposed method, have normal heat resistance, normal or 1-2 HRC units, higher hardness, 20-30% higher strength and toughness, high grain dispersity ( about 12 points) and carbits, increasing cutting resistance by 1.3–2 times.

Аналогичные результаты достигают также с применением заготовок подвергнутых пове1рхностей термической или термомеханической обработке (например поверхностной закалке , цементации, поверхностному легированию и т. п.).Similar results are also achieved with the use of blanks subjected to thermal or thermomechanical surface treatment (for example, surface hardening, cementation, surface doping, etc.).

Предмет изобретени Subject invention

Способ .получени  изделий, Преимущественно режущего инструмента, .включающий закалку, отпуск и деформацию заготовки, отличающийс  тем, что, с целью повышени  эксплуатационных качеств изделий, закаленную заготов)ку подвергают высокоскоростному , преимущественно электрическому , равномерному нагреву до ковочных температур , затем производ т скоростную с высокими степен ми деформацию ,в изотермических услови х, -в момент окончани  которой быстро охлаждают поковки, после чего осуществл ют несколько отпусков.The method of obtaining products, mainly cutting tools, including hardening, tempering and deformation of the workpiece, characterized in that, in order to improve the performance of the products, the hardened workpiece is subjected to high-speed, mainly electric, uniform heating to forging temperatures, then it is produced with high degrees of deformation, under isothermal conditions, at the moment of termination of which the forgings are rapidly cooled, after which several vacations are made.
