Abstract
A polycrystalline article is converted to a single crystal in a solid-state process. Heat is applied at a first end of the article to effect a predetermined spatial temperature profile thereat having a maximum temperature approaching a melting temperature thereof. The temperature profile is maintained to initiate conversion at the first end. The heat is moved along the article toward an opposite second end to correspondingly propagate the conversion along the article.
