Symposium Fracture: 65 Years after the Weibull Distribution and the Williams Singularity
Presentation Title Weibull Analysis of High Strength Ni- and Fe-based Bulk Metallic Glasses
Author(s) Henry J Neilson, John J Lewandowski
On-Site Speaker (Planned) Henry J Neilson
Abstract Scope In this study, the variations in mechanical properties of four Ni-based and nine Fe-based metallic glasses have been analyzed. These alloys possess very high strength (e.g. > 3 GPa) and high to very high density (8-12g/cm<sup>3</sup>). Mechanical properties were measured via a combination of Vickers hardness, bending strength, tension, compression, and toughness testing. Both bulk, e.g. cast rods and spark plasma sintered discs, and laboratory scale, e.g. melt spun ribbon, samples are analyzed. Two- and three-parameter Weibull statistics were employed to describe the variability of each property. Weibull analysis is a powerful tool that allows for comparison of the failure probability distribution for multiple materials across various testing methods. The variability in properties and their source(s) are compared to that of other engineering materials. The role of defects and volume effects are discussed to relate each test technique.
