摘要：

The phase equilibria of the Fe-Si-Ti ternary system were investigated by electron probe microanalyzer (EPMA), back scattered electron (BSE) and X-ray diffraction (XRD) on the equilibrated alloys. Twenty-four alloys of the Fe-Si-Ti ternary system were prepared. In this study, three isothermal sections of the Fe-Si-Ti ternary system at 1000, 1100 and 1200 A degrees C were respectively determined and seven ternary compounds were confirmed. The eta Fe5Si3 phase is discovered at 1100 and disappeared at 1200 A degrees C. The obtained experimental results show that there is large solubilities of Si in the TiFe2 phase. The newly determined phase equilibria of the Fe-Si-Ti system will provide useful information for the development of silicon steels.
