Abstract

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

Claims22

Dependent claims

A method for casting comprising:

forming a seed by bending at least one precursor of the seed into an arcuate form;
providing molten material;
and
cooling and solidifying the molten material so that a crystalline structure of the seed propagates into the solidifying material.
