Analysis of changes of saturation magnetization and specific volume during phase transformations of Fe-C alloys

A given work is concerned with investigation of additive properties of alloys-saturation magnetization and specific volume. The method is proposed for calculation of additive properties of alloys using experimental data. The experimental data relate to the changes of properties during the phase transformations. Such a method permits to obtain the information about the distribution of carbon in steel over,the phases and states. The corresponding equations are obtained for description of the volume changes during the tempering of quenched steel and during the austenitization, for description of changes of a saturation magnetization during the different treatments and for the quantitative analysis of the data of measurements.
