Mechanical behavior of amorphous alloys
TL;DR: In this paper, a review of recent advances in understanding the mechanical behavior of metallic glasses, with particular emphasis on the deformation and fracture mechanisms, is presented, where the role of glass structure on mechanical properties, and conversely, the effect of deformation upon glass structure, are also described.

A survey of instrumented indentation studies on metallic glasses
Christopher A. Schuh,T.G. Nieh +1 more
Abstract: The development of instrumented nanoindentation equipment has occurred concurrently with the discovery of many new families of bulk metallic glass during the past decade. While indentation testing has long been used to assess the mechanical properties of metallic glasses, depth-sensing capabilities offer a new approach to study the fundamental physics behind glass deformation. This article is a succinct review of the research to date on the indentation of metallic glasses. In addition to standard hardness measurements, the onset of plasticity in metallic glasses is reviewed as well as the role of shear banding in indentation, structural changes beneath the indenter, and rate-dependent effects measured by nanoindentation. The article concludes with perspectives about the future directions for nanocontact studies on metallic glasses.

Microstructure controlled shear band pattern formation and enhanced plasticity of bulk metallic glasses containing in situ formed ductile phase dendrite dispersions
TL;DR: Under unconstrained mechanical loading organized shear band patterns develop throughout the sample, which results in a dramatic increase in the plastic strain to failure, impact resistance, and toughness of the metallic glass.

Discrete and continuous deformation during nanoindentation of thin films
TL;DR: In this paper, Suresh et al. described nanoindentation experiments on thin films of polycrystalline Al of known texture and different thicknesses, and of single crystal Al of different crystallographic orientations.

TL;DR: In this paper, the mechanical properties of two Zr-base bulk amorphous alloys (BAA) were studied by both tensile and compressive tests at room temperature in various test environments and the results suggest that moisture-induced hydrogen embrittlement in BAAs may be masked by catastrophic fracture following shear bands.

Deformation Mechanisms of the Zr40Ti14Ni10Cu12Be24 Bulk Metallic Glass
TL;DR: In this article, the authors studied the mechanical behavior of Zr 40 Ti 14 Ni 10 Cu 12 Be 24 through uniaxial compression and nanoindentation experiments and found that shear is more likely caused by changes in viscosity associated with increased free volume in the shear bands.
