摘要

The particle characteristics such as size distribution, composition and morphology have been studied in an Fe-20mass percent Cr alloy as a function of holding time at 1600 deg C. The alloy was deoxidised with Ti and Ce, followed by holding at 1600 deg C and cooling to 1400 deg C and quenching. The inclusion particles were investigated on a surface of film filter with an open pore size of 0.05 or 5 urn after electrolytic extraction of the metal samples. Different electric charge and electrolytes (2 percent TEA and 10 percent AA) were compared for extraction of the Fe-20mass percent Cr alloy. 300 Coulombs with 10 percent AA was found most suitable for the electrolytic extraction of particles to determine the particle composition and size distribution. Most of the particles were found to be complex oxides containing Ti, Ce and Cr. Furthermore, the composition of the particles was found to change from a high Ce-content to a high Cr-content with longer holding time at 1600 deg C.
