Deterioration characterization during thermal shock testing

Thermal shock stability plays a great role in the selection of optimal refractory material. Different methods characterization were developed for this purpose, including implementation nondestructive testing. Image analysis is very well method different materials structures, as changes and occurred defects structure caused by influences. In paper, possible application image will be presented related to monitoring thermal behavior selected materials. parameters such are R parameter, level destruction, determination morphological descriptors (area, perimeter, diameter, roundness) using analysis, presented.
