Abstract Fast scanning calorimetry (FSC) based on nanocalorimetry and thin film technique is a newly developed attractive tool to investigate the solidification behavior of single droplet by in situ controllable ultrafast cooling. In this paper, we introduced this novel technique to in situ control the quenching of single Sn3.5Ag metallic droplet at cooling rate up to 15,000 K/s with corresponding undercooling of 110.9 K. In particular, the solidification structure of this real time quenched single droplet was observed and analyzed with focused ion beam (FIB), scanning electron microscopy (SEM) and high resolution transmission electron microscopy (HRTEM). This research proposed a new approach to research the solidification structure of single droplet with precisely controlled size and extreme cooling rate.
