Corrosion behaviour of AA 1370 strands for wires: Identification of the critical metallurgical parameters

Abstract : The corrosion behaviour of AA 1370 in different metallurgical states was studied in chloride-containing sulphate solutions. The microstructures of a rod, a deformed strand and an annealed strand constitutive of wires were examined using scanning electron microscopy, transmission electron microscopy and electron backscattered diffraction. Results offered evidence for the ultra-fine grain size, high density of interfaces and high level of misorientation of the interfaces as relevant explanations for the low corrosion resistance of the deformed strand compared to the rod and the annealed strand.
