Filtering by: Subject Metallic glasses -- Fatigue

Advancing the understanding of bulk metallic glasses as structural materials through exploration of mechanical properties

Creator:

Naleway, Steven E.

Abstract:

Bulk metallic glasses (BMGs) offer a great deal of potential through their near-theoretical strength, potentially high toughness and unique forming and molding traits. However, there are still a number of outstanding issues that bar their widespread use. This thesis describes the investigation of three research questions each designed to further...

Effect of ambient environment on the fracture and fatigue properties of Zr-based bulk metallic glasses

Creator:

Philo, Sarah L.

Abstract:

The effect of ambient environment on the fatigue behavior of two Zr-Ti-Cu-Ni-Be bulk metallic glasses (BMGs) is examined in the present study. The first metallic glass, Zr₄₄Ti₁₁Ni₁₀Cu₁₀Be₂₅, was tested to establish the presence of an environmental effect in the fatigue growth curve measured in ambient air. Fatigue growth curves produced...

Masters Thesis
Fatigue and fracture of bulk metallic glasses : role of free volume

Creator:

Launey, Maximilien E.

Abstract:

Deformation of metallic glasses requires the existence of free volume to allow atomic movement under mechanical loading. Accordingly, the present research seeks to understand how free volume variations in alloys of identical compositions affect the fatigue and fracture behavior. By annealing below the glass transition temperature, the free volume of...
