Testing of small-sized samples with the Brazilian test for assessment of brittle strength of metallic materials

Abstract

The article provides an experimental basis for application of the disk sample loaded by the Brazilian test method (disk compression in the diameter plane) for the brittle strength assessment of the metallic materials during testing of the small-sized samples. The research presents a strong correlation between strength of the cast iron, assessed by the testing of disk samples and the tensile strength. The method was used to study the mechanical properties of heavy tungsten pseudo-allows obtained by exposure to high-voltage electric pulse.
