As evident on the data given in our first report, the heat treatment before creep-rupture test of type 321 stainless steel presented some remarkable results on the creep rupture strength. In this study carbide changes observed in specimens before and after creep-rupture test were studied by various kinds of testing methods such as high-resolution electron-diffraction and select electron-diffracttion, etc. Carbides extracted from each specimen by chemical procedures were tested by X-ray diffraction. Carbides precipitated in all the specimens quenched from the temperature range of 1300∿800℃ before creep-rupture test were identified as titanium carbide and carbides of other kinds. The lattice constants of titanium carbide extracted had different values depending upon each different quenching temperature.
