Description
Summary:At present, there are two different resonant test methods used for the evaluation of the elastic characteristics and the coefficient of internal friction of materials. We propose a method and an automated installation aimed at the determination of the temperature dependences of the characteristics of elasticity and internal friction of metallic materials. In the course of the tests, the results of measurements of the temperature of the specimen, its resonance frequency. and the amplitude of vibrations at a given temperature are recorded in a computer. The moduli of elasticity and the characteristics of internal friction of the metal are computed at each given temperature by using the proposed relations. By analyzing the results of testing 012Kh18N10T steel, it is shown that the proposed method gives unusual results.
