A STUDY OF STRESS CORROSION CRACKING RESISTANCE FOR COLD FORMING PLASTIC DEFORMED Cu-30Zn ALLOY

EFFECT OF GRAIN-BOUNDARY STRUCTURE ON STRESS CORROSION CRACKING IN Cu-Al ALLOY BICRYSTALS

Tarnish Resistance, Corrosion and Stress Corrosion Cracking of Gold Alloys

Tarnishing, corrosion and stress corrosion cracking (SeC) of gold alloys are related phenomena. They present problems when they occur in gold jewellery, dental gold alloys and electronic devices. They are exploited, however, in the depletion gilding and finishing of gold jewellery; and in the extraction, refining and fire assaying of gold. There is still much that is not known about these pheno...

EFFECT OF INTERFACIAL STRUCTURE AND ENERGY ON CORROSION AND STRESS-CORROSION-CRACKING IN Cu-Al ALLOY BICRYSTALS

Stabilities of the symmetrical <110>and -tilt and -twist boundaries of an a Cu-AI alloy against both dissolution and Stress-Corrosion-Cracking (SCC) are discussed. The susceptibilities of the boundaries to SCC are strong1 y dependent upon the misorientation. Cusps exist at some angles which are corresponding to relatively small C-values. These boundaries indicating great resistances t...

Effect of Hydrogen on Corrosion and Stress Corrosion Cracking of AZ91 Alloy in Aqueous Solutions

The effect of hydrogen on the corrosion and stress corrosion cracking of the magnesium AZ91 alloy has been investigated in aqueous solutions. Hydrogen produced by corrosion in water diffuses into, and reacts with the Mg matrix to form hydride. Some of the hydrogen accumulates at hydride/Mg matrix (or secondary phase) interfaces as a consequence of slow hydride formation and the incompatibility ...
