ARCUATE DIRECTIONALLY SOLIDIFIED COMPONENTS AND MANUFACTURE METHODS

A method for casting comprising: providing a seed (84), the seed characterized by: an arcuate form and a crystalline orientation progressively varying along an arc of the form; providing molten material (123; 360'); and cooling and solidifying the molten material so that a crystalline structure...

Zusammenfassung:	A method for casting comprising: providing a seed (84), the seed characterized by: an arcuate form and a crystalline orientation progressively varying along an arc of the form; providing molten material (123; 360'); and cooling and solidifying the molten material so that a crystalline structure of the seed propagates into the solidifying material.
