This volume contains the edited Proceedings of the Sixth World Round Table Conference on Sintering, held in Herceg-Novi, Yugoslavia on September 2-6, 1985. It was organized by the International Institute for the Science of Sintering (IISS), headquartered in Beograd. Every fourth year since 1969, the Institute has organized such a Round Table Conference on Sintering, each has taken place at some selected lo­ cation within Yugoslavia. A separate series of IISS Summer Schools have also been held at four year intervals, but they have been offset by about two years, so they occur between the main Conferences. As a rule, the Summer Schools have been devoted to more specific topics and they also take place in different countries. The aim of these Conferences and their related Summer Schools has been to bring together scientists from allover the world who work in various fields of science and technology concerned with sinter­ ing and sintered materials. A total of six IISS Conferences have been held over the period 1969-1985, and they have been supplemented by the three Summer Schools held in Yugoslavia, Poland and India (in 1975, 1979 and 1983, respectively). This most recent five day Conference addressed the fundamental scien­ tific background as well as the technological state-of-the-art in sintering and sintered materials. It encompassed many of the high technology sintered materials needed for a wide variety of research and industrial applications.
