New parameter for assessment of structural quality - the measure of structural quality μ^σ_Pms by the residual mechanical stability Pms is offered. It exhibits their residual possibility to resist embrittlement under the stress concentration. The analysis of changes in structural quality of a number of alloys under the effect of two types of stress raisers at uniaxial tension and static bending is executed.
