Abstract
Reported measurements of the kinetics of spherodisation, coalescence and coarsening (ripening) of liquid and solid lead inclusions in aluminium are compared with theoretical predictions. The experimental results for spherodisation and coarsening of liquid inclusions above the Al–Pb eutectic temperature are in reasonable accord with predictions assuming control by diffusion of aluminium in liquid lead while those for coarsening of liquid lead spheres lie some six orders of magnitude above predictions assuming control by diffusion of lead through the aluminium matrix.
