The corrosion behaviour of binary Al–Sc alloys (Al-0.3Sc and Al-1Sc, wt%) is investigated in de-aerated 0.6 M NaCl solution, performing potentiodynamic polarisation, potentiostatic transients and electrochemical impedance spectroscopy (EIS) measurements complemented with scanning electron microscopy (SEM). In the presence of chloride ions, both...

The corrosion properties of magnesium-heavy rare earth (RE) based alloys have been studied. Binary additions of gadolinium (Gd), dysprosium (Dy) and erbium (Er) to pure magnesium were made to a nominal 1 at.%. The corrosion resistance of Mg99Gd1, Mg99Dy1 and Mg99Er1 alloys has been assessed by using open circuit potential measurements,...

Microstructural variations induced on AISI 304Cu steel disks by explosions of small charges which caused limited or null macro-deformation are illustrated. Explosions were performed in the Cottrau ballistic facility of the Italian Military Navy at La Spezia, Italy, using either 50 g or 100 g NSP explosive spherical charges (54.5 and 109 g TNT...
