Influence of anisotropy of the rolled stock mechanical properties on initiation and development of tough and lamellar-tough fractures

A.V. Bernatsky

E.O. Paton Electric Welding Institute of the NASU 11 Kazymyr Malevych Str., 03150, Kyiv, Ukraine.

Abstract
Brief description of expert estimations of service failures related to the structural texture, is given. The rationality of introduction of new terminology is presented in order to define the main kinds of lamellar fracture, namely lamellar-tough, lamellar-brittle, lamellar-fatigue and lamellar-hydrogen. A quantitative estimate of the influence of the percentage of sulphur in the base metal on the process of initiation and development of tough and lamellar-tough fractures, is given.
Keywords: anisotropy of mechanical properties, lamellar service fractures, investigations, crack resistance
