Failure analysis of re-bars during bending operations

(in lingua inglese)

From the visual observation of the failed samples chervon markrs were observed through out the locations of the centrally splitted re-bar samples. The factography analysis of the fracture surface shows predominantly cleavage facets at the surface of the failed samples. From visual and fractography analysis results the indication of brittle nature of fracture was obtained. From the microstructure analysis through harden martensitic matrix was observed from core to edge of the rebar sample with few amounts of retain austenitic structure (average 328 HV).
