This invention lies in that a seed material controlled into a predetermined orientation is joined to a treating material under an activated state of joint face or through an interposition of an insert member and heated to a temperature causing grain boundary movement to render a whole of a joined body into a crystal body having a predetermined crystalline orientation. Furthermore, not only plate material and bar material but also coil can be used as the treating material, so that crystal bodies having excellent desired properties can be mass-produced with a good yield and in industrial scale,
L'invention a pour caractéristique qu'un germe contrôlé dans une orientation prédéterminée est ajouté à une matière de traitement par activation de la surface de joint ou par interpositionnement d'un insert et chauffé à une température faisant intervenir le mouvement du joint de grains, de manière à transformer un corps lié en un corps cristallin ayant une orientation cristalline prédéterminée. La matière de traitement peut consister en une matière en plaque, en barre et en spirale, de sorte que les corps cristallins possédant les caractéristiques souhaitées peuvent être produits en grande quantité et à l'échelle industrielle.
