    摘要: 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.
