Изобретение относитс к испытательной технике и может быть использовано при испытании материалов на длительную пластичность при малых скорост х деформировани .The invention relates to a testing technique and can be used when testing materials for long-term ductility at low deformation rates.
Цель изобретени повышение информативности испытани путем увеличени достижимой степени деформации .The purpose of the invention is to increase the informative value of the test by increasing the degree of deformation that can be achieved.
На чертеже изображено устройство дл осуществлени способа.The drawing shows a device for implementing the method.
Устройство содержит раму, состо щую из основани 1, направл ющих 2, неподвижной траверсы 3 и подвижной 4 с прикрепленным к ней грузом 5. Соответственно на неподвижной 3 и подвижной 4 траверсах закреплены захваты 6 и 7 дл установки стержн 8 и захваты 9 и 10 дл установки испытуемых образцов 11. На неподвижной траверсе 3 установлен нагреватель 12, охватывающий стержень 8.The device comprises a frame consisting of a base 1, guides 2, a fixed cross beam 3 and a movable 4 with a weight 5 attached to it. Accordingly, the fixed arms 3 and 7 for mounting the rod 8 and the grips 9 and 10 for fixed installation of the test specimens 11. On the fixed traverse 3 is installed a heater 12, covering the rod 8.
Способ осуществл етс следующим образом.The method is carried out as follows.
Металлический стержень 8, например из меди, устанавливают в захватах 6 и 7 и нагружают с помощью груза 5, прикрепленного к подвиж32 .A metal rod 8, for example of copper, is installed in grippers 6 and 7 and is loaded with the help of a load 5 attached to a slide 32.
ной А траверсе. Затем стержень нлгревагот и после того, как в течение первых часов нагрева стержень 8, получив начальное удлинение, завершит стадию неустановившейс ползучести, в,захваты 9 и 10 устанавливают испытуемые образцы 11.Noah And traverse. Then the nlgrewot rod and after the core 8, during the first hours of heating, having obtained the initial elongation, completes the stage of unsteady creep, in, the grippers 9 and 10 set the test samples 11.
Увеличение сопротивлени деформированию за счет деформационного упрочнени испытуемых образцов 11 компенсируетс уменьшением сопротивлени деформированию стержн 8 за счет уменьшени площади его попербчного сечени . При необходимости возможно регулирование процесса путем корректировки массы груза 5. Так как деформаци ползучести металличес кого стержн больше, чем дефЬрмаци того же стержн за счет термического расширени (например, дл стержн из меди 7% вместо 2%), то достижима степень деформации исследуемых . образцов при их испытании увеличиваес , что позвол ет получить сведени об исследуемом материале в большем диапазоне деформаций и, следовательно , повысить информативность испытани .The increase in the resistance to deformation due to the deformation strengthening of the tested samples 11 is compensated by the decrease in the resistance to deformation of the rod 8 due to the decrease in the area of its cross section. If necessary, it is possible to regulate the process by adjusting the mass of the load 5. Since the creep deformation of the metal rod is greater than the deflection of the same rod due to thermal expansion (for example, for a copper rod 7% instead of 2%), the degree of deformation of the studied is achievable. Samples during their testing increases, which allows to obtain information about the test material in a larger range of deformations and, consequently, increase the information content of the test.
