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.

The invention relates to a process for producing, by casting between rolls, an aluminum alloy sheet suitable for making up constituent elements of cans for food use, the aluminum alloy containing (by weight) between 1 and 4% of Mg and between 0 and 1.6% of Mn, the process being characterized in that said sheet is obtained by casting of said alloy in the liquid state between two rolls in the form of a strip having a thickness of at most 4 mm followed by at least one heat treatment at a temperature between 400.degree. and 580.degree. C. so that the sheet is at least partially recrystallized and cold-rolling to a final thickness of less than 0.3 mm.The sheet obtained has a yield stress, a formability index and a resistance of the coating to delamination which are improved and make it suitable for application to can manufacture and, in particular, to can lids.
摘要:
Rolled or extruded products for welded constructions made of AlMgMn type aluminum alloy. These products contain, in % by weight, 3.0 0.75. In the welded state, these products have improved mechanical strength and resistance to fatigue without unfavorable consequences with regard to toughness and corrosion resistance, and are particularly suitable for naval construction, for industrial vehicles and for bicycle frames made of welded tubes.
