摘要：

Sintering of compacted metal powders is investigated by small-angle neutron-scattering techniques. The results evaluated in terms of the total pore surface area F and the total pore volume V give evidence for a universal relation between F and V thus indicating that both coarsening and pore elimination contribute to the surface reduction during the sintering process.
