STRESS-GRAIN SIZE ANALYSIS OF THE BRITTLE FRACTURE TRANSITION OF STEEL

Abstract

The temperature interval in which steel may show a fairly abrupt change from ductile to brittle behavior has been quantitatively specified in terms of the (Hall-Petch) stress-grain size parameters already reported in the literature from tests at various temperatures and strain rates. The transition in behavior depends in an important way on each one of all the stress components normally combined in a single yield stress or fracture stress measurement.
