ABSTRACT:
Disclosed is a method of making moldless/coreless single crystal castings of NiAl(.beta.') alloys. Drops of molten NiAl(.beta.') alloy is deposited on a starter seed block of single crystal alloy and casting structures are epitaxially grown to predetermined configurations and shapes by repeatedly dropping and solidifying molten NiAl(.beta.') materials.
