Abstract

An automated system with two optimized modular devices is presented—MULTITEST-MC010 for research of ferromagnetic materials with the methods for measuring magnetic noise and magneto acoustic emission of Barkhausen and MULTITEST—CD010 for research of mechanical engineering materials with the methods of velocity measurement of longitudinal waves C and attenuation coefficient δ of ultrasound. The main approaches and principles for the automated data processing of complex non-destructive testing are presented, as well as the setup of the modular devices of the automated system. For approbation of the system the influence of the heat treatment (hardness) in structural steel 40X on the non-destructive information parameters of the magnetic noise and the magneto acoustic emission—magnetic noise voltage E_BN and voltage of the magneto acoustic emission E_MAE was studied. The mechanical properties in foundry cast iron samples with complex measurement of the information parameters E_BN, E_MAE C, by simultaneous use of the two modular devices of the system were also studied. The possibility for the complex application of these parameters for non-destructive testing of the mechanical properties after heat treatment in structural steel 40X and the tensile strength in cast iron specimens has been proven.
