title = "Measurement of steel phase transformation kinetics by dilatometry and in-situ neutron diffraction - A comparative study",
abstract = "Solid-state phase transformation kinetics between ferrite (α) and austenite (γ) phases in a C-Mn steel were investigated by the dilatometry and in-situ neutron diffraction methods, respectively. Dilatometry is commonly used to study the phase transformation kinetics. It infers the allotropic phase transformation from the overall dimensional changes, e.g., the diameter changes of the specimen, during heating and/or cooling. In this regard, it is an indirect measurement technique. Alternatively, neutron diffraction directly detects and measures the individual phases as they present during different stages of phase transformation. A comparative study was made in this work between the dilatometry and the in-situ neutron diffraction methods. The comparison shows that dilatometry analysis would cause the under-estimation of austenite phase evolution as a function of temperature due to the drastic deviation of linear expansion assumption of austenite as function of temperature.",
