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

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...

ELECTROCHEMICAL NOISE ANALYSIS OF 70-30 BRASS DURING STRESS CORROSION CRACKING TEST IN MATTSON S SOLUTION

An investigation of the electrochemical noise generation during Stress Corrosion Cracking (SCC) of 70-30 Brass in Mattson's solution was conducted. The fluctuations of potential and current were monitored. The relationship between potential and current fluctuations has been evaluated in time domain and the obtained data has been analyzed in the frequency domain using Power Spectral Density (PSD...

Corrosion Product Film-Induced Stress Facilitates Stress Corrosion Cracking

Finite element analyses were conducted to clarify the role of corrosion product films (CPFs) in stress corrosion cracking (SCC). Flat and U-shaped edge-notched specimens were investigated in terms of the CPF-induced stress in the metallic substrate and the stress in the CPF. For a U-shaped edge-notched specimen, the stress field in front of the notch tip is affected by the Young's modulus of th...
