Novel Deformation Processing of Amorphous MEMS
Abstract
Novel Deformation processing of amorphous metals has been conducted on a variety of metallic glasses. Both large scale (e.g. 10's mm size) and small scale (e.g. sub-micrometer size) deformation processing has been conducted using some of the unique properties exhibited by metallic glasses. In all cases, the intermediate temperature properties of metallic glasses (e.g. Zr-, Cu-, Fe-, Al-, Hf-based) have been determined using a NIKON-QM2 Hot Microhardness Machine. Once the effects of changes in test temperature were determined, novel deformation processing of various shapes was conducted. Both fine scale features (i.e. sub-micrometer) as well as larger scale structures were replicated. In addition, the temperature rise near shear bands in bulk metallic glasses was determined using novel nano-scale coatings designed to provide high spatial and temporal resolution. Finally, the fracture toughness of metallic glass/W composites was determined. These materials were processed by others to determine their potential use as advanced penetrator materials.
