摘要：
The kinetics of spreading and solidification of liquid droplets on cold substrates are considered. It is shown that for low wetting situations with contact angles >π/2, the time for spreading needed for the liquid droplet to attain its equilibrium shape is much shorter than the time for the onset of solidification. It is concluded that under these conditions the solidification droplet shape corresponds to that of the liquid at its melting temperature. The surface tension of liquid Fe-Si-B is derived from its droplet's shape on a copper substrate.
