“…On the other hand, it is also clarified that the alloys suffer pitting corrosion during anodic polarization in NaCl solution due to the existence of Zr and Al elements. This result is in agreement with previous work that Zr-based glassy alloys 26) and the alloys containing Zr 27) suffer pitting corrosion in chloride containing solutions. Moreover, it is well known that Nb element is an effective alloying element to provide a high passivating ability for the metallic glasses.…”

New Cu-based bulk glassy alloys with good mechanical properties were formed in Cu-Zr-Al-(Nb) system by copper mold casting. They exhibit a large supercooled liquid region (ÁT x ) of 50 K-74 K and high glass-forming ability with maximum diameters of 2.0 mm-3.0 mm. The addition of Nb to the glassy alloys is effective for improving the corrosion resistance in all the solutions. The corrosion rate of the 5 at% Nb alloy decreases by one order of magnitude compared to those of the 0 at% Nb alloys in 3 mass% NaCl solution. In 0.5 molÁdm À3 H 2 SO 4 solution, the Cu-Zr-Al-(Nb) alloys are passivated in wide passive region and low passive current density of the order of 10 À2 AÁm À2 , indicating high corrosion resistance in this solution.

Effects of yttrium and erbium additions on glass-forming ability (GFA), thermal stability and mechanical properties of glassy Zr 55 Al 10 Ni 5 Cu 30 alloy were studied. (Zr 0:55 Al 0:10 Ni 0:05 Cu 0:30 ) 100Àx RE x (RE = Y, Er and x ¼ 0; 0:5; 1; 2; 3; 5 at%) metallic glasses were formed by melt-spinning and copper mold casting. It was found that the addition of Y or Er greatly enhanced the glass-forming ability, thermal stability and mechanical properties of Zr 55 Al 10 Ni 5 Cu 30 alloy. The alloys containing 1-3 at% Er can be cast into glassy rods with a diameter of 15 mm, which is larger than the critical diameter (10 mm) of the base alloy in the present work. With the addition of 1 at% Y, supercooled liquid region ÁT x of the base alloy was extended from 89 to 102 K, compressive strength was increased from 1650 to 1800 MPa and plastic strain reached a value as high as 3.5%.

“…This gives rise to rapid pit growth and low repassivation. Their pitting susceptibility and repassivation ability can be significantly influenced by alloying elements [24][25][26][27][28][29]. In a recent study, both these properties were found to depend strongly on Cu concentration [30].…”

Stress-corrosion interactions in materials may lead to early unpredictable catastrophic failure of structural parts, which can have dramatic effects. In Zr-based bulk metallic glasses, such interactions are particularly important as these have very high yield strength, limited ductility, and are relatively susceptible to localized corrosion in halide-containing aqueous environments. Relevant features of the mechanical and corrosion behavior of Zr-based bulk metallic glasses are described, and an account of knowledge regarding corrosion-deformation interactions gathered from ex situ experimental procedures is provided. Subsequently the literature on key phenomena including hydrogen damage, stress corrosion cracking, and corrosion fatigue is reviewed. Critical factors for such phenomena will be highlighted. The review also presents an outlook for the topic.
