- Аннотация: The article investigates the possibility of determining the resistance to fracture of materials obtained from powders by electric pulse consolidation method using the test method for bending thin disks on an annular support and testing short cylinders according to the "Brazilian test". Techniques are verified by testing small-sized thin disks and short cylinders made of gray cast iron and graphite. It is revealed a difference in the nature of the destruction of cast iron samples (plastic failure) and samples of graphite (brittle fracture). The good correspondence of the characters of destruction of graphite samples and samples produced from powders by the electric pulse consolidation is shown. The influence of various additives and manufacturing technology of materials on the resistance of the material to brittle fracture is revealed. The optimal modes of high voltage consolidation a heavy alloy based on the results of tests of short cylinders according to the “Brazilian test” scheme were obtained. The effect of the thickness of the cylinders on the strength of aluminum oxide Al2O3 is investigated.
