После прот жки измен ют угол наклона участков 1, 2 канала и осуществл ют дополнительную прот жку образца 3 со скоростью, отличной от скорости первой прот жки, приближа параметры пластического деформировани материала к реальным услови м. 1 ил. 1 табл.The invention relates to a test technique and permits the investigation of the mechanical properties of materials during their plastic deformation. The purpose of the invention is to improve the accuracy of testing materials obtained by pressure treatment by approaching the deformation conditions to the processing conditions. The deformation of sample 3 of the material is carried out by drawing at a constant speed along a channel of constant section, having two straight linear sections 1 and 2 inclined to each other. After drawing, the angle of inclination of sections 1, 2 of the channel is changed and additional sample drawing 3 at a speed different from that of the first pass, approximating the parameters of plastic deformation of the material to actual conditions. 1 Il. 1 tab.

Изобретение относитс к испытательной технике, а именно к способам исследовани механических свойств материалов при их пластическом де- формироватш.The invention relates to a testing technique, in particular, to methods for studying the mechanical properties of materials at their plastic deformation.
Цель изобретени - повышение точности испытаний материалов, получае- ьых обработкой давлением, путем приближени условий деформировани к услови м обработки.The purpose of the invention is to improve the accuracy of testing materials obtained by pressure treatment, by approaching the deformation conditions to the processing conditions.
На чертеже изображена схема реализации .предлагаемого способа.The drawing shows the implementation scheme. The proposed method.
Способ осуществл ют следующим образом .The method is carried out as follows.
Два пр молинейных участка 1 и 2 канала посто нного сечени наклон ют друг к другу. Осуществл ют деформирование образца 3 материала прот жкой с посто нной скоростью по этому каналу. После прот жки образца 3 материала измен ют угол наклона участков 1 и 2 канала и осуществл ют дополнительную прот жку образца 3 со скоростью, отличной от скорости первой прот жки, приближа тем самым услови деформировани материала к реальньм услови м его обработки давлением . IThe two rectilinear sections 1 and 2 of the constant section channel are inclined towards each other. The material 3 is deformed by drawing at a constant speed through this channel. After material 3 is pulled, the angle of inclination of sections 1 and 2 of the channel is changed and additional sample 3 is drawn at a speed different from the speed of the first one, thereby bringing the material to a deformed condition to the real conditions of its pressure treatment. I
Пример. По предлагаемому способу осуществл ют одноразовую прот жку образцов сечением 510 мм из стаExample. According to the proposed method, a one-time drawing of samples with a cross section of 510 mm from one hundred is carried out.

Результаты приведены в таблице и показывают, что предлагаемый способ позвол ет определ ть напр жени б р сдвига и мощность W сдвиговой деформации от параметров пластического деформировани о&разцов материалов т.е. получить их значени дл условий реальной обработки материалов давлением.This is where L b ORA and calculate the shear stresses and the power W of their shear strain. The same values are determined according to the 2nd theory of strength. The results are shown in the table and show that the proposed method allows one to determine the shear stress and the shear strain power W from the plastic strain parameters of the material samples, i.e. to obtain their values for the conditions of real processing of materials by pressure.
