Quality of Precipitation Annealing of Heat-Resistant Cast Steel using a Taguchi Analysis

Popis výsledku v původním jazyce

In this study, the effects of temperature and time on the hardness of heat-resistant cast steel HK30 Nb obtained with centrifugal casting were analysed using the Taguchi method. On the basis of the analysis of the obtained results, we reached reliable conclusions on the improvement of the exploitation properties. The tests showed that precipitation annealing of a HK30 Nb casting can improve the exploitation properties at high temperatures. The defined temperature and holding time comply with the results of the mathematical analysis of the achieved properties, and the presumed research theory from this study can hence be confirmed. The studies showed that the mechanical properties improved during the precipitation-annealing process. During this process, significant transformations of the carbide phase occur in the microstructure, thereby changing its morphology, distribution, size and composition, which was confirmed by testing the microstructure with a scanning electron microscope.
