Abstract:

The spheroidization of cementite in binary iron-carbon alloys was investigated over a range of temperatures 594, 649, and 704C for times up to about a million seconds. Quantitative metallography techniques were used to obtain the following microstructural data on the cementite particles shape, size distribution, mean size, number of particles per unit volumes, and growth and shrinkage rates of various sizes in the size distribution. The variations of these microstructural parameters were analyzed in terms of existing models for the spheroidization process.
