Description

Примен емые способы термомеханической обработки металлов и сплавов путем совмещени  операций термической обработки и пластической деформации не обеспечивают необходимой степени упрочнени  металлов и сплавов.The applied methods of thermomechanical treatment of metals and alloys by combining heat treatment and plastic deformation do not provide the necessary degree of hardening of metals and alloys.

Описываемый способ термомеханической обработки металлов и сплавов путем совмещени  операций термической обработки и пластической деформации позвол ет повысить сопротивление ползучести, например , у нержавеющей стали и железа армко более чем в дес ть раз.The described method of thermomechanical processing of metals and alloys by combining heat treatment and plastic deformation allows to increase the creep resistance of, for example, stainless steel and Armco iron more than ten times.

Достигаетс  это тем, что издели  после полного цикла термической обработки, предусматриваемого дл  обрабатываемой стали или иного сплава, дополнительно подвергают деформированию при повышенной температуре, а затем выдерживают при той же температуре уже без нагрузки.This is achieved by the fact that the products, after a full cycle of heat treatment envisaged for the steel or other alloy being processed, are additionally deformed at an elevated temperature, and then maintained at the same temperature without any load.

Необходимое деформирование издели  можно осуществл ть путем прокатки, посредством статического раст жени  или же медленным деформированием при посто нном раст гивающем усилии на заготовку (путем ползучести).The required deformation of the product can be carried out by rolling, by static stretching, or by slowly deforming with a constant tensile force on the workpiece (by creep).

Деформирование производ т до критической величины в 0,2-3,0% при температуре, соответствующей услови м будущей эксплуатации издели  с допустимыми отклонени ми ее на ±50°, однако не выще температуры начала рекристаллизации сплава.The deformation is performed to a critical value of 0.2–3.0% at a temperature corresponding to the conditions for the future operation of the product with its tolerance of ± 50 °, however, not more than the temperature at which the alloy begins to recrystallize.

Последующа  термическа  обработка без нагрузки производитс  в течение час. при той же температуре, при которой производилось деформирование металла.Subsequent thermal processing with no load is performed within an hour. at the same temperature at which the metal was deformed.

Всесоюзный научно-исследовательский и конструкторский институт химического мащиностроени  в своем заключении отмечает, что при предлагаемом способе обработки металлов и сплавов можно примен ть при повыщенных температурах и длительных напр жени х менее леги№ 1438252рованные стали. В особенности способ пригоден дл  обработки труб, деформаци  которых может быть осуществлена наиболее просто.The All-Union Scientific Research and Design Institute of Chemical Engineering, in its conclusion, notes that with the proposed method of treating metals and alloys it is possible to use at elevated temperatures and long-term stresses less light steel No. 1438252. In particular, the method is suitable for processing pipes, the deformation of which can be carried out most easily.

Предмет изобретени Subject invention

Способ термомеханической обработки металлов и сплавов путем coв #eщeнн  операций термической обработки и пластической деформации , о-т л ичающийс  тем, что, с целью повышени  жаропрочности, издели  после обычной термической обработки подвергают дополнительному деформированию до критической степени деформации при температуре , не превышающей температуру начала рекристаллизации и затем выдерживают при этой температуре в течение 20-50 час без нагрузки .The method of thermomechanical processing of metals and alloys by means of heat treatment and plastic deformation operations, which is due to the fact that, in order to increase heat resistance, the product after the usual heat treatment is subjected to additional deformation to a critical degree of deformation at a temperature not exceeding the onset temperature recrystallization and then maintained at this temperature for 20-50 hours without load.
