THE METHOD OF DETERMINING THE TEMPERATURE OF DUCTILE-BRITTLE TRANSITION

摘要

The method of determining the temperature of ductile-brittle transition, in which at a consistent temperature changes alternately put effort to n-elements are produced in monolithic sample and have cuts, deforming them to destruction, recording acoustic emission impulses that arise in the brittle fracture temperature ductile-brittle transition determined by a function of temperature settings pulses of acoustic emission brittle fracture of individual elements. Make like a plate in which at least one end items produced in the form of teeth, efforts to put their free limbs from where incisions are made to their complete destruction. To determine the temperature of ductile-brittle transition using parameters that depend on the number of pulses brittle fracture of individual elements and the amounts of their amplitudes.
