Small punch tensile/fracture test data and 3D specimen surface data on Grade 91 ferritic/martensitic steel from cryogenic to room temperature

Raw data from small punch tensile/fracture tests at two displacement rates in the temperature range from −196 °C to room temperature on Grade 91 ferritic/martensitic steel are presented. A number of specimens were analyzed after testing by means of X-ray computed tomography (CT). Based on the CT volume data detailed 3D surface maps of the specimens were established. All data are open access and available from Online Data Information Network (ODIN)https://odin.jrc.ec.europa.eu. The data presented in the current work has been analyzed in the research article “On the determination of the ductile to brittle transition temperature from small punch tests on Grade 91 ferritic-martensitic steel” (M. Bruchhausen, S. Holmström, J.-M. Lapetite, S. Ripplinger, 2015) [1].

Small punch tensile/fracture test data for P92 nt material at -150 °C and a displacement rate of .00833 mm/s

Data collection containing small punch tensile/fracture data for tests on Grade 91 ferritic/martensitic steel performed between cryogenic and room temperatures. The material has the same chemical composition as P91/ T91 but is supplied in form of a plate rather than as pipe (P91) or tube (T91). The particular batch of Gr. 91 used in the present work (S50460) as part of the FP7 project MATTER was originally produced for the FP6 project EUROTRANS (project domain 4: DEMETRA). Disc-shaped small punch (SP) specimens as specified in the European Code of Practice were used. Their diameter was 8 mm and their thickness 0.5 mm. The surface roughness was less than Ra = 0.15 um on both sides. SP tensile/fracture mechanics tests were performed with varying displacement rates and temperatures as listed in Table 1. On the specimens tested at 0.5 mm/s X-ray computed tomography analysis has been carried out and the 3D surface has been reconstructed.

Small punch tensile/fracture test data for P92 material at 23 °C and a displacement rate of .00833 mm/s

Small punch tensile and creep data obtained in a round robin exercise for the elaboration of an EN standard on small punch testing. For estimating the tensile properties a series of tests were carried out at room temperature on Gr. 91 steel with different heat treatments. Further tests were performed at varying temperatures between 77K and room temperature to determine the ductile to brittle transition temperature (DBTT). Creep tests were carried out at temperatures in the range 550-650 oC.
