“…For instance, the atomic percentage of Zr is higher in the matrix than in dendrites with a factor of 1.2. As a passive film forming agent, Zr seems more efficient than Ti in terms of metal activity and capacity to the capture of O [26]. Thus, it is inferred that higher Zr content in the matrix is responsible for the observed preferred dissolution of the crystalline dendrites.…”

Abstract:In-situ metallic glass matrix composites (MGMCs) are a new kind of promising structural engineering material. In this study, a comprehensive study about the corrosion behavior of in-situ Ti 46 Zr 20 V 12 Cu 5 Be 17 MGMCs versus their size was conducted. It is interesting to find that the large sample exhibits a more excellent corrosion resistance than the small sample in the 10% H 2 SO 4 solution both in chemical and electrochemical tests at room temperature. Furthermore, the results obtained from X-ray photoelectron spectra (XPS) demonstrate that the quality of the passive film formed on the large-sized sample is indeed superior to the small-sized sample. Based on (scanning electron microscope) SEM observation, the possible mechanisms of the observed phenomenon have been discussed in the present study.

“…New Ni-based bulk glassy alloys which are free from metalloids and have high strength and ductility have been synthesized in the NiNb-based alloy system by melt-spinning and copper-mold casting methods [18]. It is well known that Ni-based metallic glasses have excellent corrosion resistance and high thermal stability [19]. Inoue et al reported the development of new Ni-based metallic glass alloys with high chemical stability and good mechanical properties [20].…”

Ni-based amorphous alloys with surface modification by carbon ion implantation are proposed as an alternative bipolar plate material for polymer electrolyte membrane fuel cells (PEMFCs). Both Ni60Nb20Ti10Zr10 alloys with and without carbon ion implantation have corrosion resistance as good as graphite as well as much lower contact resistance than 316L stainless steel in the PEMFC environment. The formation of conductive surface carbide due to carbon ion implantation results in a decrease in the contact resistance to a level comparable to that of graphite. This combination of excellent properties indicates that carbon ion implanted Ni-based amorphous alloys can be potential candidate materials for bipolar plates in PEMFCs.

“…[1][2][3][4][5] However, monolithic BMGs usually exhibit no plastic deformation after yielding during room-temperature deformation due to the formation of highly localized shear bands, [6][7][8][9][10] which significantly limits the range of applications as structural materials. The motivation to improve the ductility of those monolithic BMGs leads to the development of BMG-based composites.…”

The rate-dependent deformation of Zr 38 Ti 17 Cu 10.5 Co 12 Be 22.5 bulk metallic-glass-reinforced porous tungsten matrix composites was investigated over a wide range of strain rates. The composites were examined in two forms: the as-cast composite and the as-extruded composite by extrusion. In addition to showing greater strain hardening, the as-cast composite also shows much more obvious strain rate dependence of flow stress than the as-extruded composite. Microhardness tests were performed on the tungsten and the metallic glass phase in both composites, respectively. The results from the microhardness measurements indicate that the strain rate sensitivity of the as-extruded composite is primarily a result of strain rate sensitivity of the tungsten phase.
