Badania propagacji pęknięć przy cyklicznym zginaniu dla różnych materiałów zgrzewanych wybuchowo

This paper describes fatigue cracks growth in three different bimetallic made by explosive cladding. In any case, it was the same base material - carbon steel P355NH, and clad materials are: austenitic stainless steel 316L, 254SMO and super duplex (50% ferritic structure, 50% of the austenitic structure). Specimens of rectangular cross-section was subje ted to fatigue bending with of the stress mean value equal zero and of constant amplitude equal to 19.41 N•m. The crack propagation was measured using a portable microscope with a micrometer located on the fatigue stand.
