The review, based on the publications by both Russian and international researchers, presents an analysis of the problems of existing technologies for smelting copper concentrates. Three main problems requiring solutions were identified and considered: increasing the efficiency of smelting copper sulfide-containing ores by reducing the copper conte...
The paper presents the results of experimental studies of the destruction of fillers of polymer composite materials (PCM) with the control of acoustic emission (AE) signal parameters. As object of research were considered silica filaments К11С6-180, carbon filaments UKN-M-12K-1-7-380 and aramid technical fiber Rusar-С600 type А. Based on the experi...
The paper presents the results of verification calculation on the crack resistance of a high-pressure cylinder taken out of service due to the detection of crack-like defect. The critical dimensions of cracks, at which brittle failure of the cylinder can occur, and the safety coefficient of the cylinder in terms of crack resistance, are determined....
The article presents the results of experimental estimation of the possibility
of early registration of structural defects using the acoustic-emission
method of control, based on the phenomenon of acoustic emission, which
is the excitation of elastic vibrations of the material, caused by the
formation and development of defects. To confirm the poss...
The analysis results of known methods for assessment of the resistance of steels and alloys to intercrystalline corrosion cracking are given. Based on the identified shortcomings, a new method of monitoring and diagnostics is proposed, which allows one to carry out an express-assessment of the tendency of steels and alloys to corrosion cracking (de...
To The article provides information on the results of studying the parameters of acoustic emission signals during the destruction of the liner material and micro-plastic of the power shell of a metal-composite high-pressure cylinder. B-200 within the framework of a complex of studies to create an acoustic-emission portrait of metal-composite high-p...
