...Peter Renner; Yan Chen; Ming Li; Chao Ma; Dilworth Parkinson; Hong Liang Additively manufactured metals such as stainless steels have promising futures because of their adaptive and one-step fabrication. However, an understanding of their properties and behavior in corrosive environments has...

...Viranshu Kumar; Ratnesh Kumar Gupta; Ghanshyam Das The as-received as well as deformed microstructure and electrochemical corrosion behavior of warm-forged and annealed 316LN austenitic stainless steel have been investigated by using electron backscatter diffraction (EBSD) and electrochemical...

...Shanavas Shamsudeen; Edwin Raja Dhas John AA 5052 H32 aluminum alloy is one of the most commonly used materials in the marine environment due to its good formability, good weldability, and better corrosion resistance. Assessment of resistance of welds of the alloy against corrosion is necessary...

...B. Aydin Baykal; Preet M. Singh Erosion-corrosion is a type of corrosion in which mechanical (erosive) and chemical (corrosive) effects combine to accelerate material loss because of corrosion because of its negative impact on the reformation of a protective oxide layer on a metal surface. Erosion...

...Bruce R. Crawford; Alexandra Shekhter; Chris Loader This article describes a project in which the Retrogression and Re-aging (RRA) heat treatment was demonstrated to be a viable means of improving the corrosion resistance of 7075-T651 components of the Royal Australian Air Force AP-3C and C-130J-30...

...Galtiere C. Rêgo; Rafael M. Bandeira; Ricardo T. Aureliano, Jr.; Amadeu N. Lombardi; Luiz C. Casteletti; George E. Totten The large economic and environmental impact caused by corrosion of metal structures has demanded new types of anti-corrosion coatings. This study proposes the application...
