Processing of Bulk Metallic Glass
Advanced Materials, 2010AbstractBulk metallic glass (BMG) formers are multicomponent alloys that vitrify with remarkable ease during solidification. Technological interest in these materials has been generated by their unique properties, which often surpass those of conventional structural materials.

Nanopatterned Bulk Metallic Glass Biosensors
ACS Sensors, 2017Nanopatterning as a surface area enhancement method has the potential to increase signal and sensitivity of biosensors. Platinum-based bulk metallic glass (Pt-BMG) is a biocompatible material with electrical properties conducive for biosensor electrode applications, which can be processed in air at comparably low temperatures to produce nonrandom ...

Bulk Metallic Glass: The Smaller the Better
Advanced Materials, 2010AbstractBulk metallic glasses (BMGs) are strong, highly elastic, and resistant to wear but still find limited utility due to their macroscopic brittle nature, high costs, and difficulty of processing, particularly when complex shapes are desired. These drawbacks can be mitigated when BMGs are used in miniature parts (< 1 cm), an application which ...

General nanomoulding with bulk metallic glasses
Nanotechnology, 2015Bulk 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).

Intermetallics, 2003
Abstract In the last decade metallic glasses have regained considerable interest due to the fact that new glass-forming compositions have been found that have a critical cooling rate of less than 100 K/s and can be made glassy with dimensions of 1 cm or more.

Combinatorial development of bulk metallic glasses
Nature Materials, 2014The 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.

“Work-Hardenable” Ductile Bulk Metallic Glass
Physical Review Letters, 2005Usually, monolithic bulk metallic glasses undergo inhomogeneous plastic deformation and exhibit poor ductility (< 1%) at room temperature. We present a new class of bulk metallic glass, which exhibits high strength of up to 2265 MPa together with extensive "work hardening" and large ductility of 18%. Significant increase in the flow stress was observed

Superductile bulk metallic glass
Applied Physics Letters, 2006Usually, monolithic bulk metallic glasses undergo inhomogeneous plastic deformation and exhibit poor ductility (<2%) at room temperature. We report a newly developed Pd–Si binary bulk metallic glass, which exhibits a uniform plastic deformation and a large plastic engineering strain of 82% and a plastic true strain of 170%, together with initial

Diffusion in bulk metallic glasses
Applied Physics Letters, 2020Due to the simple structure, bulk metallic glasses are very convenient model systems for studying the mechanism of atom diffusion in disordered media. In this paper, we analyze literature data on diffusion for a set of atoms in the metallic alloy Zr46.75Ti8.25Cu7.5Ni10Be27.5 (Vitreloy 4) above and below the glass transition temperature.

Bulk stiffnesses of metallic glasses
Journal of Applied Physics, 1982Determinations 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.
