The characteristics of planed defects in (Cr,Fe)7C3 in a chromium steel and two kinds of cast alloys have been delineated.Combining matrix analysis of electron diffraction pattern with calculated angle between planed detect traces and using compound reciprocal space composed of matrix cell and two rotative cells,the [011] and [013] planed defects in (Cr,Fe)-C3 have been determined in an all-round way.A crystallographic model for (Cr.Fe)2C3 has been proposed.
