Casting of Intermetallics

Despite of the significant effort has been dedicated to featuring the properties of elevated temperature intermetallics, melting, and casting techniques for such materials have been slightly developed. A mixture of methods may be applicable for the melt processing of intermetallics, however, assigning the process will be according to various considerations associated to solidification microstructure, sort of alloys, and melt cleanliness. In this review article, casting of three different alloys (near-gamma titanium aluminide and two types of nickel aluminide) is investigated. Advanced casting technologies are applied such as melt and casting technology, cast microstructure, production readiness, exo-melt process, equiax casting, and DS casting technology.
