The change in nucleation behavior of a metal alloy sample studied using a Differential Scanning Calorimeter is displayed in this presentation. The sample was previously heated above its liquidus temperature, and the peaks in the graph show heat released during nucleation and solidification of the under-cooled liquid. The change in nucleation behavior occurs as a function of the substrate morphology that changes during the repeated cycling. The data sets from 61 measurements (traces) were stored in individual worksheets. The graph combines data plots corresponding to all the traces in one layer. Text labels have been added to the graph to indicate the order of the traces.
