THE EFFECTS OF GAMMA-RAY ON THE MECHANICAL PROPERTIES OF Zr-BASED BULK METALLIC GLASS
The effect of gamma-ray irradiation on the mechanical properties of Zr55Ni5Al10Cu30 bulk metallic glass (BMG) was investigated. The samples were irradiated with a gamma-ray dose up to 2090.24 kGy prior to mechanical property investigations. Vickers hardness test, nano-indentation test as well as speed of sound measurements in order to calculate the material’s elastic moduli were conducted. An x...
متن کاملMicrostructure and mechanical properties of electron beam weld joints of a Zr41Ti14Cu12Ni10Be23 bulk metallic glass with Zr
The electron beam welding technique was used to join Zr41Ti14Cu12Ni10Be23 bulk metallic glass (BMG) to crystalline pure Zr. Compositional, microstructural, and mechanical property variations across the welded interface were evaluated. It is shown that a crystalline layer develops close to the welding interface. Transmission electron microscopy of this layer indicates the crystalline phase to be...
متن کاملEBSD Analysis for Microstructure Characterization of Zr-based Bulk Metallic Glass Composites
Bulk metallic glasses (BMG’s) have long been materials of interest due to their high strength, high elastic limit, wear and corrosion resistance, and ease of thermoforming above the glass transition temperature [1]. The primary technical challenge of implementing BMG’s in engineering applications is their tendency to fail catastrophically via highly localized shear banding events. Though the el...
متن کاملEffect of Loading Rate on Dynamic Fracture Morphology of a Zr-Based Bulk Metallic Glass
Low-velocity plate impact experiments using a single-stage gas-gun are performed on Zr58.5Cu15.6Ni12.8Al10.3Nb2.8. Compressive fracture surfaces of the samples subjected to varying impact velocities and stress amplitudes are evaluated in order to study their loading rate dependence. Samples impacted at increasing loading rates, from increasing velocities of impact, show a larger extent of local...
متن کاملEffect of high strain rates on peak stress in a Zr-based bulk metallic glass
The mechanical behavior of Zr41.25Ti13.75Cu12.5Ni10Be22.5 LM-1 has been extensively characterized under quasistatic loading conditions; however, its mechanical behavior under dynamic loading conditions is currently not well understood. A Split–Hopkinson pressure bar SHPB and a single-stage gas gun are employed to characterize the mechanical behavior of LM-1 in the strain-rate regime of 102–105 ...
