Pore coarsening, frequently observed during sintering, is usually regarded as a consequence of pore migration with the grain boundaries. Experimental observations on grain growth and pore coalescence during heat treatment of copper, reported in the present work, however support the conclusion that the major mechanism of pore coarsening is Ostwald ripening by a grain boundary diffusion process rather than grain boundary controlled pore migration.
