About the concentration range of homogeneity of cementite in iron-carbon alloys

Abstract

Abstract On the basis of X-ray analysis and quantitative metallography to determine the minimum content of carbon in cementite eutectic - coordinate of the point F of the binary phase diagram of the Fe-Fe3C. The results are checked by calculation using data on saturation magnetization, which gave a good quantitative agreement. Given the preliminary nature of the results presented conclusions about the larger than previously estimated, the width of the field homogeneity cementite and feasibility correction on this basis of heat treatment alloys, carbide grade.
