A method for making a metal structure comprising: (i) selectively grit-blasting a part of a major surface of the metal sheet at a temperature lower than the annealing temperature of the metal sheet to impart a stress in the metal sheet; and (ii) subjecting the metal sheet to a heat treatment at a temperature not lower than T(anneal) - 400°C so that the metal sheet deforms, such that the deformed metal sheet exhibits a higher strength in a desired direction, wherein T(anneal) is the annealing point of the metal. The invention is particularly advantageous for making thin Pt metal structures for glass melting, conditioning, delivery and forming operations. |
