Abstract (en)
[origin: CA3128294A1] The invention discloses a method for producing a sheet or strip from an aluminium alloy, and a sheet, strip or shaped part produced thereby. A rough surface and flow patterns can be avoided if the cold-rolled sheet or strip of a particular composition and microstructure is subjected to a heat treatment including recrystallization annealing with subsequent accelerated cooling.
