General nanomoulding with bulk metallic glasses

Nanotechnology, 2015
Bulk metallic glasses (BMGs) are ideal for nanomoulding as they possess desirable strength for molds as well as for moldable materials and furthermore lack intrinsic size limitations. Despite their attractiveness, only recently Pt-based BMGs have been successfully molded into pores ranging 10-100 nm (Kumar et al 2009 Nature 457 868-72).

Combinatorial development of bulk metallic glasses

Nature Materials, 2014
The identification of multicomponent alloys out of a vast compositional space is a daunting task, especially for bulk metallic glasses composed of three or more elements. Despite an increasing theoretical understanding of glass formation, bulk metallic glasses are predominantly developed through a sequential and time-consuming trial-and-error approach.

Bulk Metallic Glass Micro Fuel Cell

Small, 2012
Micro fuel cells (MFC) have been identifi ed as promising alternative power sources for portable electronics. Using noncorrosive electrolytes, they offer high theoretical power densities at low operating temperatures, with the potential for stable long-term operation.

Metallic glass fiber-reinforced Zr-based bulk metallic glass

Scripta Materialia, 2011
A novel Zr-based bulk metallic glass composite was fabricated using stainless steel capillaries as the reinforcement. Large plasticity (14%) was achieved in the composite with a reinforcement volume fraction of 38%. The high plasticity observed can be attributed to the formation of small glass fibers encapsulated by the steel capillaries, which ...

Bulk stiffnesses of metallic glasses

Journal of Applied Physics, 1982
Determinations of density, Vickers microhardness, Young’s modulus, and Poisson’s ratio are reported for a series of Fe-B glasses, for glassy Fe40Ni38Mo4B18, and for glassy Cu68Zr32. From the last two parameters, one may calculate the shear and bulk stiffnesses of the glasses.

Tantalum based bulk metallic glasses

Journal of Non-Crystalline Solids, 2011
Ta-based bulk metallic glasses with high strength (2.7 GPa) and hardness (9.7 GPa), high elastic modulus (170 GPa) and high density (12.98 g/mm(3)) were developed. The best glass forming ability so far for a Ta-Ni-Co system reaches a critical diameter of 2 mm by the copper mold casting method. It shows an exceptionally high glass transition temperature

Zinc-based bulk metallic glasses

Journal of Non-Crystalline Solids, 2010
We report the fabrication and properties of zinc-based bulk metallic glasses (BMGs). The formation mechanism of the BMGs is also discussed. The combination properties of high corrosion resistance, low glass transition temperature T(g) and high formability, low Young's modulus and density, low cost, harmless components to organisms and tunable ...

Bulk metallic glass tube casting

Journal of Alloys and Compounds, 2011
Abstract Tubular bulk metallic glass specimens were produced, using a custom-built combined arc-melting tilt-casting furnace. Zr55Cu30Al10Ni5 tubes with outer diameter of 25 mm and 0.8–3 mm wall thicknesses were cast, with both tilt and suction casting to ensure mold filling.

Aluminum-rich bulk metallic glasses

Scripta Materialia, 2008
The formation and properties of a class of Al-rich bulk metallic glasses (BMGs) are reported. The Al contents for these alloys can reach up to 40 at.%, which is the highest in known BMGs. The Al-rich BMGs deviate greatly from eutectic composition and show high thermal stability and fragility, and very high mechanical strength.

Bulk metallic superconductive La60Cu20Ni10Al10 glass

Journal of Non-Crystalline Solids, 2005
Abstract A bulk metallic superconductive La60Cu20Ni10Al10 glass with highly glass forming ability and large supercooled liquid temperature region is developed. The superconductive critical temperature determined by the electrical resistance and the specific heat measurements is 2.5 K.
