Целью изобретени вл етс обеспечение возможности испытани материалов с упрочненным слоем при высокой точности.Это достигаетс выполнением образца в виде полого цилиндра с рабочей 2 и захватными 3 част ми и выполнением упрочненного сло 4 по всей внешней поверхности образца на глубину,не менее толщины рабочей части 2. 1 ил. оThe invention relates to the study of the mechanical properties of materials, in particular to the determination of the strength properties of samples with a pre-strengthened surface layer. The aim of the invention is to provide the possibility of testing materials with a hardened layer with high accuracy. This is achieved by making the sample in the form of a hollow cylinder with working 2 and gripping 3 parts and making the hardened layer 4 across the entire outer surface of the sample to a depth not less than the thickness of the working part 2 .1 il. about

Изобретение относитс к исследовани м механических свойств материалов, |а именно к определению прочностных Р.ВОЙСТВ образцов с предварительно уп- очненным поверхностным слоем. : Цель изобретени - обеспечение возможности испытани материала с |упрочненнЬ1м слоем при высокой точности .The invention relates to the study of the mechanical properties of materials, | namely, to the determination of the strength properties of samples with a previously packed surface layer. A: The purpose of the invention is to enable material to be tested with a | hardened layer with high accuracy.
На чертеже показан предлагаемый |эбразец.The drawing shows the proposed | ebrazetz.
Образец состоит из полого цилиндра 11, имеющего рабочую часть 2 и захват- йые части 3, на всей внешней поверх- йости образца выполнен упрочненный слой 4, толщина стенки рабочей части Образца 2 меньше или равна глубине упрочненного сло ; захватные час.ти 3 Снабжены резьбовыми отверсти ми, от рабочей части 2 к захватным част м 3 выполнены плавные переходы.The sample consists of a hollow cylinder 11, having a working part 2 and gripping parts 3, a reinforced layer 4 is made on the entire outer surface of the sample, the wall thickness of the working part of Sample 2 is less than or equal to the depth of the strengthened layer; gripping parts 3 Equipped with tapped holes, smooth transitions are made from working part 2 to gripping parts 3.
Испытани образца провод т следую- фим образом.Samples were tested as follows.
; В захватные части 3 образца ввер- тывают резьбовые захваты, закрепл ют rtx в зажимах испытательной машины.; Screw clamps are screwed into the gripping parts 3 of the specimen, fastened rtx in the clamps of the testing machine.
нагружают его, и по результатам испытаний суд т о механических свойствах материала.load it, and according to the results of tests judged the mechanical properties of the material.
Предлагаемый образец обеспечивает в процессе испытани повьшшнную точность испытани за счет того, что в рабочей части образца упрочненный сло выдел етс в чистом виде, а переход от рабочей части образца к захватным част м не имеет концентраторов напр жени на наружной упрочненной поверхности.The proposed sample provides in the process of testing an increased test accuracy due to the fact that in the working part of the sample the hardened layer is distinguished in its pure form, and the transition from the working part of the sample to the gripping parts does not have a voltage concentrator on the outer hardened surface.
