Title (EN) ALUMINUM ALLOY HAVING VISIBLE GRAINS AND ALUMINUM ALLOY COLORED BY DOUBLE ANODIZATION
(FR) ALLIAGE D'ALUMINIUM AYANT DES GRAINS VISIBLES ET UN ALLIAGE D'ALUMINIUM COLORÉ PAR DOUBLE ANODISATION
Abstract:
(EN) Embodiments relate to a type of aluminum alloy with grains visible to naked eyes. The aluminum alloy may have an average grain size of at least 100 μηι. The aluminum alloy can be produced by a process such as casting, extrusion, solutionizing, aging, and etching. The solutionizing causes recrystallization of aluminum and causes grains of the aluminum to grow. Compared with the solutionizing, the aging is performed at lower temperature but enhances strength of the aluminum alloy. The etching makes grain boundaries of the aluminum alloy more prominent, rendering the grains of the aluminum alloy visible to a naked human eye.
(FR) Des modes de réalisation de la présente invention concernent un type d'alliage d'aluminium avec des grains visibles à l'œil nu. L'alliage d'aluminium peut avoir une taille de grain moyenne d'au moins 100 μm. L'alliage d'aluminium peut être produit par un procédé tel que la coulée, l'extrusion, la mise en solution, le vieillissement et la gravure. La mise en solution entraîne la recristallisation de l'aluminium et cause la croissance des grains de l'aluminium. Par rapport à la mise en solution, le vieillissement est effectué à une température inférieure mais augmente la résistance de l'alliage d'aluminium. La gravure rend les joints de grain de l'alliage d'aluminium plus proéminents, de façon à rendre les grains de l'alliage d'aluminium visibles à l'œil nu humain.
