Abstract: The invention relates to a method for the deformational transformation of aluminum and its alloys comprising the steps of deforming the aluminum in the solid state and annealing the deformed aluminum at a temperature at which recrystallization occurs. The recrystallization temperature of the aluminum is raised and the grain size is minimized by adding to the aluminim 5 to 1000 ppm uranium prior to the deformation. The method is particularly applicable to the production of aluminum based sheets intended to be subjected to heating at a relatively high temperature, for example the heating which accompanies enamelling or brazing operations, where the heating operation could change the mechanical properties of the sheets.

Abstract: The invention relates to a method of making sheets of aluminium suitable for drawing.The method according to the invention comprises subjecting the product issuing from a continuous casting machine to a mechanical cleaning treatment and then to a controlled heat treatment in air at elevated temperature.The method according to the invention is applicable in every case where aluminium products, such as strips etc. are subjected to drawing or reducing operations and in cases where it is desired to eliminate galling phenomena and to guarantee aesthetic qualities. The method according to the invention is used in particular in the manufacture of cans from blanks obtained by casting between cylinders.
