Abstract
A method of manufacturing a replacement body for a component is provided. The method includes the steps of: a) additively manufacturing a crucible for casting of the replacement body; b) solidifying a metal material within the crucible to form a directionally solidified microstructure within the replacement body; and c) removing the crucible to reveal the directionally solidified replacement body.
Claims15
A method of manufacturing a replacement body for a component, comprising:
- additively manufacturing the replacement body with a metal material;
- forming a core at least partially within the replacement body;
- at least partially encasing the replacement body and the core within a shell;
- melting the additively manufactured replacement body;
- solidifying the metal material of the additively manufactured replacement body to form a directionally solidified microstructure within the component;
- and
- removing the shell and the core to reveal the directionally solidified microstructure replacement body.
