Dilatometry is the most accurate and common method for measuring the kinetics of phase transformations in solid specimens. Despite the development of a more accurate technique, an inferior method, i.e., the lever rule, is widely used in the scientific community to interpret raw dilatometry data. This paper introduces a sound mathematical approach to modelling the physical phenomena of phase transformations, named continuous sequential phase transformation (CSPT). CSPT is used in creating an algorithm called unit cell dilation (UCD) that is used for analyzing the continuous phase transformation of two microalloyed steels. Results show that the UCD algorithm generates quantitative data for the phase content of the steel that is in good agreement with metallographic observations.
