grain fineness sand. The foam pattern degrades immediately after molten metal is introduced‚ leaving a casting that duplicates all features of the foam pattern. The degradation products are vented into the loose sand. In lost foam casting process‚ mold filling‚ thermal transport‚ and solidification are strongly influenced by the foam pattern degradation. There are three phenomena which are inherent in lost foam casting process: slow molten metal flow‚ reducing atmosphere‚ and degradation

NANOFABRICATION AND SCANNING PROBE LITHOGRAPHY Introduction: “Nanofabrication” is the process of making functional structures with arbitrary patterns having minimum dimensions currently defined (more-or-less arbitrarily) to be e100 nm. Microelectronic devices and information technologies have improved and will continue to improve as a result of large-scale‚ commercial implementation of nanofabrication. The motivation for these improvements is to increase the density of components
