NEW DEVELOPMENTS IN FOREIGN METHODS OF RATING THE TENDENCY OF STRUCTURAL STEELS TO BRITTLE FRACTURE

Abstract

An evaluation of the tendency to brittle fracture is important with respect to the material of welded sructures where favorble conditions exist for the formation of brittle fractures,AND ESPECIALLY FOR THEIR DEVELOPMENT INTO A THROUGH-FRACTURE. Investigators have tried to account for these conditions when developing new test methods. In the majority of investigations fracture tests were conducted to determine the characteristics of ductility, and the area of the fracture diagram. Notched bars are the most widely sed for fature tests. Fracture tests on smooth and notched bars at lower temperatures are considerably more frequent now than in the prewar period; bending is also used. (Author)
