Abstract

The article presents results of studies of silicon – molybdenum cast iron crystallization process. This material is use to work in high temperatures. The study included experimental melting (estimated chemical composition was: 4.5 %Si; 2.5 %Mo; 2.5 %C) and analysis of crystallization process. For examination the TDA equipment was used for registration of temperature changes in time and for calculation of derivative curve. The analysis of chemical composition of obtained samples using spectrometer GDS500A and Leco analyser was conducted. Metallographic examination of cast alloys was carried out on Phenom Pro-X scanning microscope. In order to determine the phase composition, X-ray diffraction studies of analyzed samples were performed. This studies were carried on the Panalytical X'Pert PRO diffraction system, using filtered radiation from the lamp with copper anode and PIXcel 3D detector on the diffracted beam axis. Obtained results allowed to described the crystallization process of ductile silicon – molybdenum cast iron (SiMo) designed to work in high temperatures. It was also possible to identify the elements of microstructure.
