| 520 | _ | _ | |a Novel developed refractories with reduced carbon content for application in steel industry were investigated regarding to their thermo-mechanical behaviour. Another major part of this work was focused on the development and trial of new/optimization of established test methods (thermal shock by heating via electron beam and wedge splitting test). Al$_{2}$O$_{3}$ with the addition of 2.5 wt.% ZrO$_{2}$ and TiO$_{2}$ respectively (AZT) leads to animproved thermal shock behaviour compared to pure Al$_{2}$O$_{3}$ materials. Temperature dependent investigations revealed a thermal hysteresis of elastic modulus, shear modulus, Poisson's ratio and thermal expansion, accompanied by a phase transformation of ZrO$_{2}$ (monoclinic $\rightarrow$ tetragonal). High temperature (800 - 1000 $^{\circ}$C) wedge splitting tests were performed with optical notch opening determination for Al$_{2}$O$_{3}$ and AZT. The phase transformation of ZrO$_{2}$ leads to a more brittle behaviour of AZT at 800 $^{\circ}$C compared to room temperature. Different loading configurations for the wedge splitting test were tested using Alumina and Al$_{2}$O$_{3}$-C materials in order to apply the test method on small specimen geometries (40 X 40 X 20 mm$^{3}$). Promising results were obtained from a simple approach using two rollers into a grooved sample. With this method, it was possible to determine a constant (sample material independent) friction coefficent ($\mu$ = 0,13). The results showed a good agreement with experimental data obtained from compact tension tests. Thermal shock tests by heating using the electron beam facility JUDITH 1 allowed the application of a well distributed loading pattern on MgO-C Materials. Temperatures up to 1400 $^{\circ}$C at the surface were achieved. The main damage was observed within the MgO grains. |
