Homogeneous nucleation and crystallization model of aluminium droplet based on isothermal DSC analysis
Original language description
The aluminum (Al) sample was studied using differential scanning calorimetry (DSC) at non-isothermal and isothermal conditions. The first non-isothermal measurements were performed by melting the Al sample and then cooling it down at rates 2 to −20 ◦ C/min to detect the crystallization temperature T C ≈ 642 ◦ C. On the contrary, the crystallization event was repeatedly detected by the isothermal DSC after several tens of minutes at the temperature T ≈ 653 to −654 ◦ C. The kinetic equations of Al crystal nucleation were solved numerically, to determine the size distribution of nuclei and the nucleation rate. Numerical solution of kinetic nucleation equations showed that a decrease in Al atoms in the liquid droplet was predominantly a consequence of the formation of the subcritical clusters. The number of nuclei reached a quasi-stationary size distribution at a sufficiently long time, for which an analytical approach for the number of critical nuclei was determined.
