Abstract of the dataset | The fracture mechanical properties of coarse-grained MgO-C were investigated in four-point bending tests at single-edge V-notched beams (SEVNB) at room and high temperature. For measurement of the crack mouth opening displacement (CMOD) an optical system was used. Room temperature tests were accompanied with microstructural observations of the crack path with the use of digital image correlation to investigate the mechanisms of crack propagation and to determine the crack length. MgO-C showed stable crack propagation at room temperature as well as up to 1500°C. Increased fracture toughness KIc and work of fracture were observed in the temperature range from 700°C to 1200°C. This behavior was correlated with crack closure, quasi-plastic deformation as well as the activation of visco-plastic creep mechanisms above 1200°C. Additionally, the results were discussed in terms of Hasselman’s thermal shock parameters. | |

Project abstract | The focus of the doctoral research project P2 within the research training group GRK2802 was the evaluation of the thermo-mechanical properties of commercial MgO-C bricks, which were supplied by the industrial partner, Refratechnik Steel GmbH. The research concentrated on three grades of MgO-C bricks: while material F was produced exclusively from virgin raw materials, the two materials R contained 47.5 wt.-% MgO-C recyclate, which, however, possessed different carbon contents due to different sources of the recyclates. | |
