Atomistic simulations of radiation damage in amorphous metal alloys
… regarding the mechanisms of radiation damage in amorphous alloys. Knowledge of collision cascade dynamics is lacking, both with respect to the possibility of sub-cascade formation and concerning the types of damage created in individual cascades. This Thesis resolves these knowledge gaps through …

Thermolysis Route for Accessing Amorphous Metal Sulfide Thin-Film Catalysts for the Hydrogen Evolution Reaction
In this work, low temperature thermolysis of metal ethyl xanthates (M = Mo, Co, Fe, Ni) was used to prepare amorphous metal and mixed metal sulfide films on fluorine-doped tin oxide for the hydrogen evolution reaction (HER). Films prepared by dip-coating showed optimal coverage, as monitored by …

Modeling the mechanical behavior of amorphous metals by shear transformation zone dynamics
… technique for the thermo-mechanical behavior of amorphous metals is proposed. The modeling framework considers the shear transformation zone (STZ) as the fundamental unit of deformation, and coarse-grains an amorphous collection of atoms into an ensemble of STZs on a mesh. By employing finite …

Diffusion and the thermal stability of amorphous copper-zirconium
… been made of diffusion and thermal relaxation in amorphous CU50Zr50. Samples were prepared by melt-spinning under vacuum. Diffusion measurements were made over the temperature range from 317 to 385 C, using Ag and Au as substitutional impurities, by means of Auger electron spectrometry (AES) and …

Mechanics, Design, and Fabrication of Metal-Graphene Composites
In the last decade, metal-graphene composites have seen significant progress and have received increasing attention because of graphene's ability to improve the mechanical properties. The main mechanism of improvement in metal graphene composite is based on the impeding of dislocations by graphene …

The Effect of Carbon Concentration on the Amorphization and Properties of Mechanically Alloyed Cobalt-Carbon Alloys
Magnetic alloys that are amorphous exhibit soft magnetic properties; hence they play an essential role in electronic and electrical systems and devices. They are used in applications that include electrical power generation and transmission, electronic motors, solenoids, relays, magnetic shielding, …
