Abstract
	Two ways of practical implementation of AE-method are shown. The first way it is monitoring of quality of materials with the help of AE measurements during laboratory research, which is called «Quality monitoring of materials» (used during mechanical, corrosion and other tests), the second it is AE-monitoring of processing of materials and AE-monitoring of work conditions of technological equipment, which is called «Technological monitoring». The results of a study of the mechanism and kinetics of metallic material fracture (dual phase steels, binary and multicomponental zirconium alloys, multifilamentary superconductors and composition wires) are given. The quantity fracture analysis is based on measurements of acoustic impulse peak (maximum) amplitudes by non-resonance sensors for linear measurement of acoustic shifts and crack parameters measurement. The developed methods of absolute calibration of AE equipment were checked by testing various types of materials and crack parameter measurements in laps and fractures. The calibration dependencies for quantity measurements are shown. The possibilities of AE for quality analysis and for characterizing of materials in the process of mechanical and other tests and in the process of pressure processing with the help of a developed experimental computerized AE system are demonstrated.
