Melting and casting processes for high-temperature intermetallics

Melting and Solidification Overview


Although considerable effort has been devoted to characterizing the properties of high-temperature intermetallics, melting and casting processes for these materials have been slower to advance. A variety of techniques may be appropriate for the melt processing of intermetallics, but the selection of the process will depend on numerous factors related to melt cleanliness, solidification microstructure and type of alloy. Advanced processes, such as directional solidification and single-crystal growth, still require some work before they can be successfully applied to intermetallics.
