Efforts were concentrated on numerically modeling the time-dependent particle coarsening (Ostwald ripening) process. Four models were included: Lifshsitz-Slyozov-Wagner, Brailsford and Wynblatt, Marqusee and Ross, and Marder. The simulations monitored the particle size distribution (PSD) as a function of time; initial PSDs were derived from classical nucleation theory. The ripening kinetics can be represented as a plot of the second moment of normalized PSD vs time. A geometric correction factor is discussed. Future research is planned on Al-Li.
