Corrosion and stress corrosion cracking of ultra-high-purity Mg5Zn

This paper reports on the measurement of the corrosion rate, and the stress corrosion cracking threshold stress, for ultra-high-purity Mg-5Zn. The corrosion rate was higher than the intrinsic corrosion rate of ultra-high-purity Mg, attributed to the quality of the corrosion product film. The threshold stress for stress corrosion cracking, at an applied stress rate of 0.00016 MPa s -1 , was equal to 0.7 times the yield stress in air. The ductility of the cracking indicated that the stress corrosion cracking mechanism was probably hydrogen enhanced localized plasticity.

“…Heat treatment can dissolve such a 15/01/09 distribution of second phase, and remove the possibility of IGSCC. In contrast, transgranular stress corrosion cracking (TGSCC) can occur in distilled water, indicating that no deleterious ions are needed [18,19,20]. TGSCC involves hydrogen [21].…”

Fracture mechanics based techniques can be used to study the phenomena of stress corrosion cracking and hydrogen embrittlement and to model the degradation of metallic materials caused by the uptake of atomic hydrogen. Constant extension rate tensile experiments were performed on both smooth and pre-cracked specimens of Mg alloys at various strain rates in a corrosive environment and, for reference, in laboratory air. The experiments show the embrittlement caused by theuptake of atomic hydrogen which is generated in the corrosion reaction of the magnesium . It is discussed whether these experimental findings can be simulated and to some extent rationalised by applying a mesoscale model which has previously been used to mimic the effect of hydrogen embrittlement in steels.
