| Abstract: | The Thermodynamics and the properties of the Fe4Ce4C7 phase in steel have been studied by means of metallography,electron microprobe and X-ray diffraction technique. The Fe4Ce4C7 phase in steel can be seperated from the matrix by electrolysis. The cerium as solid solute in steel is inclined to collect about cerium carbide. On heating at high temperature,if ac
