Document Summary

Create a program that computes the volume fraction of alpha phase as a function of temperature and time. Output- fa = volume fraction of alpha phase. V_ =1. 7*10^-5 % m^3/mol, volume per mole gamma = . 01 % j/m^2, surface tension omega = 1*10^13 % hz, vibration frequency of atoms. Dgm = 50208 % j/mol, energy required for atomic migration v_0 = 10^6 m/s % initial velocity. % calculates delta g or change in free energy from latent heat(l) and temp(t) and uses the transition temperature(t_tr)% % calculates the velocity of the particle growth from the initial velocity(v_0), change in free energy(dg) % setup if else statement to calculate the radius of a cluster, ri(t+1), and radius of growth of existing% %clusters, ri(t), as a function of time and saves each iteration in an array% % i indicates the time step that a new cluster is nucleated% i = 1.
