abstract = "The effect of heating rate on the phase transformation kinetics from ferrite (α) and martensite (αM) to austenite (γ) in advanced high-strength steels (AHSS) was investigated. With the unique stroboscopic pump-probe neutron diffraction technique, a time-resolution of 0.1 second or less, corresponding to a time increment of 3°C or less, was achieved. A trend was clearly observed indicating that higher heating rate causes a wider and higher temperature range for the a to γ transformation. The lattice spacing change associated with the austenite formation on heating was obtained as well, which decreases at the early stage of transformation process and increases at the latter stage as a function of temperature. The kinetics governing such observed non-equilibrium phase transformation phenomena is discussed.",
