Numerical modelling of the surface cracking tendency in solidifying ceramic materials

Popis výsledku v původním jazyce

EUCOR is a ceramic material resistant to extreme heat and wear. A block made of EUCOR with dimensions of 350 x 200 x 400 mm was used for the numerical calculation and the experiment. The numerical model of the casting block temperature field determines the temperature gradients, the solidification rate and the local solidification time (i.e., the time between the liquidus and solidus temperatures). The local solidification time significantly affects the forming of the pouring structure of the given material and it makes one of the input parameters for the second cooperating chemical heterogeneity model. This model and its application on EUCOR samples prove that the applied measuring method of the chemical heterogeneity provides detailed quantitative information on the material structure and makes possible the analysis of the solidification process. The analysis of this process entails statistical processing of results of the heterogeneity measurements of the EUCOR components and it per
