Description

Изобретение относитс  к снособам термомеханнческой обработки изделии.This invention relates to methods for thermo-mechanical treatment of an article.

Известен способ термомеханической обработки изделий, включающий пластическую деформацию , отпуск и закалку.The known method of thermomechanical processing of products, including plastic deformation, tempering and quenching.

Однако этот способ не обеспечивает удовлетворительной усталостной прочности издev ий.However, this method does not provide satisfactory fatigue strength of products.

Цель изобретени  - повышение усталостной -прочности изделий.The purpose of the invention is to increase the fatigue strength of products.

Это достигаетс  тем, что пластической деформации подвергают поверхность издели , пластическую деформацию производ т при 20-400°С, а также тем, что пластическую деформацию произ1вод т во врем  нагрева под отпуск.This is achieved by subjecting the surface of the product to plastic deformation, plastic deformation is performed at 20-400 ° C, and also by plastic deformation during heating during tempering.

Описываемый способ включает холодную или «теплую пластическую деформацию поверхности издели  при 20-400°С, например, путем обкатки роликовым приспособлением (с целью изменени  дислокационной структуры поверхности), а также отпуск при 250- 450°С (с целью протекани  процессов полигонизации и деформационного старени ) и закалку со скоростного индукциоииого.пагрева; две последние операции могут быть произведены с помощью индуктора и спрейера, совмещенных с приспособлением дл  обкатки. После закалки возможно проведение окончательного отпуска.The described method includes cold or "warm plastic deformation of the product surface at 20-400 ° C, for example, by rolling with a roller device (to change the dislocation structure of the surface), as well as tempering at 250-450 ° C (for the purpose of polygonisation and deformation). aging) and quenching from high-speed induction; the last two operations can be performed using an inductor and a sprayer, combined with the device for running. After quenching, it is possible to conduct a final vacation.

Описываемый способ опробован при обработке предварительно улучщепных пзделий из стали 4 ОХ. Режим обработки включал обкатку поверхности врап ающегос  издели  на глубину 3-5 мм с помощью роликового приспособлени  при удельном давлении 80-120 кг1мм, отпуск при 400°С, механическую обработку , скоростной индукционный нагрев до (, закалку и око11чательный отпуск.The described method was tested in the processing of pre-upgraded apparel steel of 4 OH. The treatment mode included running in the surface of the falling product to a depth of 3-5 mm using a roller device at a specific pressure of 80–120 kg1 mm, tempering at 400 ° C, mechanical processing, high-speed induction heating to (, quenching and finishing tempering).

Усталостна  прочность обработанных изделий увеличилась на 15-20%.Fatigue strength of the processed products increased by 15-20%.

Благодар  повыщению усталостной прочности изделий применение описываемого способа термомехапической обработки позвол ет увеличить рессурс изделий.Due to the increase in the fatigue strength of the products, the use of the described method of thermomechanical treatment allows increasing the resource yield of the products.
