Abstract

Differential thermal analysis experiments and treatments for 50 h at 1000, 1100 and 1200 °C were performed for a binary Fe30Cr alloy and for six Fe30Cr (0.2 to 2 wt.%) C alloys. A complete metallographic characterization was done for all samples. The solidus and liquidus temperatures, the natures and the surface fractions of the carbide and matrix phases were determined for the three temperatures. They were compared to thermodynamic calculation results. The values and the evolutions of the solidus temperature versus the carbon content are in good agreement between experiment and calculations. It is less true for the carbide volume fractions which were obtained either by image analysis, or from the matrix Cr content. Mismatches were also observed for the liquidus temperature. Comparisons were done with the Co30CrxC and Ni30CrxC systems and with Ta-containing Fe30CrxC alloys.

Keywords: Iron-based alloys; Chromium carbides; High temperatures; Microstructure
