Abstract
Method of determining the stress of irreversible displacement of dislocations at loading of metals, through which in parallel with the diagram of loading is carried out the analysis of emissive acoustic signals within the range of frequencies of 100-150 kHz, which are emitted by moving dislocations. The range of zones are determined by changes in the quantity of signals per unit of time. The stress of the beginning of irreversible displacement of dislocations is defined by appearance of acoustic signals, which are i 50 % of background values.
