摘要：

Phase equilibria in selected phase regions of the Fe-Cr-Ni and Fe-Cr-C systems were investigated at the temperatures 795 °C, 900 °C and 1000 °C. The fcc/bcc, fcc/(σ phase) phase equilibria in Fe-Cr-Ni system and fcc/bcc/M23C6, fcc/M7C3/M23C6, bcc/M23C6 phase equilibria in Fe-Cr-C system were investigated. The wavelength dispersive microanalysis for bulk specimens, carbon layer extraction technique for carbide composition analysis, and electron diffraction phase identification on foils were applied. The new information concerning fcc/(σ phase) phase region of the Fe-Cr-Ni system at 900 °C is presented and the precision to M23C6 carbide equilibria in the Fe-Cr-C system at 1000 °C is given.
