Thermomechanical properties of mullitic materials

Popis výsledku v původním jazyce

Mechanical tests provide important information about the properties and behaviour of materials. Basic tests include the measurement of flexural strength and in case of refractory materials, the measurement of flexural strength at high temperatures as well. The dependence of flexural strength on the temperature of ceramic materials usually exhibits a constant progression up to a certain temperature, where the material starts to melt and so the curve begins to decline. However, it was discovered that ceramic mullitic material with a 63 wt.% of Al2O3 exhibits a relatively significant maximum level of flexural strength at about 1000 degrees C and refractory mullitic material with a 60 wt.% of Al2O3 also exhibits a similar maximum level at about 1100 degrees C. The mentioned maximum is easily reproducible, but it has no connection with the usual changes in structure of material during heating. The maximum was also identified by another measurement, for example from the progression of the dynamic Young&apos;s modulus or from deflection curves. The aim of this work was to analyse and explain the reason for the flexural strength maximum of mullitic materials at high temperatures.
