Description

The file contains experimental results for seven different layerwise compositions of Ti Gr 1, Zr 700 alloys, and carbon steels subjected to fully reversed cyclic axial loading. This work was supported by the National Centre for Research and Development, Poland [grant number Techmastrateg2/412341/8/NCBR/2019].

Steps to reproduce

The analysed data set included seven multilayer plates with a corrosion-resistant layer (flyer plate) made of Zr 700 alloy or Ti Gr 1 alloy. The flyer sheet was directly welded to the base plate (three cases) or through the interlayer (four cases). All multilayer plates were fabricated at ZTW Explomet (Opole, Poland). The specimens were cut from the multilayer plates with an initial thickness reduced by milling. The original plate thickness was reduced to adapt the cross-sectional area of the specimen to the applied capacity of the hydraulic fatigue machine (±50 kN). The specimens were subjected to fully reversed cyclic loading under force-controlled loading. Failure was defined as complete specimen separation, and the number of loading cycles (sinusoidal signal) to failure was counted based on this definition. The strain signals were recorded using a mechanical extensometer mounted on a steel layer with a gauge length of 25 mm.
