Изобретение относитс к области И1сследовани прочностных свойств материалов, а именно к способам испытани материалов на термостойкость.The invention relates to the field of investigation of the strength properties of materials, and in particular to methods of testing materials for heat resistance.
Известный способ испытани материалов на термостойкость за ключаетс в том, что образец кольцевой формы нагревают, размеща во внутренией целости пагреватель, и фиксируют величину термического расширени , по которой суд т о термостойкости материала.A known method of testing materials for heat resistance is that a sample of an annular shape is heated, placing the heater inside, and the amount of thermal expansion determined by which the heat resistance of the material is measured.
Недостатком известного способа вл етс сложность процесса испытапи , поскольку он требует применени мощного нагревател и использовани образцов кольцевой формы.The disadvantage of this method is the complexity of the testing process, since it requires the use of a powerful heater and the use of ring-shaped samples.
По предлагаемому способу используют слержпевой образец, который размещают между концами скобы, имеющей жесткость, пр мо пропорциоцальную модулю упругости материала образца и приращению его длипы. Это упрощает процесс испытани .According to the proposed method, a sample sample is used, which is placed between the ends of a bracket having a rigidity directly proportional to the elastic modulus of the sample material and the increment of its length. This simplifies the testing process.
Изготовл ют стержневой образец из испытуемого материала и скобу, имеющую жесткость , пр мо пропорциональную модулю упругости материала образца п приращению его длины. Затем образец размещают между концами скобы и нагревают, например, пропускaн;Ie i тока. В процессе нагрева фиксируют величину термического расширени образца, по которой суд т о термостойкости материала .A core sample is made of the test material and a bracket having a rigidity directly proportional to the elastic modulus of the sample material and an increment of its length. Then the sample is placed between the ends of the bracket and is heated, for example, by passing; Ie i current. In the process of heating, the amount of thermal expansion of the sample is recorded, according to which the heat resistance of the material is judged.
