Bulk Metallic Glasses Porous Mg Scaffolds Carbon Nanotube Formation

A NEUTRON AND X-RAY DIFFRACTION STUDY OF Ca-Mg-Cu METALLIC GLASSES (Preprint)

The structures of Ca60Mg15Cu25, Ca60Mg20Cu20 and Ca60Mg25Cu15 metallic glasses have been investigated by neutron and X-ray diffraction. The correlation functions show a peak manifold in the region 2.2 Å to 4.5 Å, arising from the various atom pairs for these glasses. The results show clearly that there are contacts between the solute atoms (Cu and Mg) in agreement with a simple estimate of the ...

Stress-corrosion crack growth of Si-Na-K-Mg-Ca-P-O bioactive glasses in simulated human physiological environment.

This paper describes research on the stress-corrosion crack growth (SCCG) behavior of a new series of bioactive glasses designed to fabricate coatings on Ti and Co-Cr-based implant alloys. These glasses should provide improved implant fixation between implant and exhibit good mechanical stability in vivo. It is then important to develop an understanding of the mechanisms that control environmen...

Nanoscale Solute Partitioning in Bulk Metallic Glasses

Adv. Mater. 2008, 20, 1–4 2008 WILEY-VCH Verlag Gmb A T IO N Fundamental understanding of composition variations and morphology in the nanoscale is essential to the design of advanced materials. Partial crystallization or devitrification of bulk metallic glasses (BMGs) results in novel microstructures, with high density (10–10m ) nanocrystalline precipitates evenly distributed in a glassy matri...

Shear Band Formation in Bulk Metallic Glasses

In recent times, there has been a growing interest in the machining of amorphous metallic alloys, which are also called bulk metallic glasses (BMGs). These materials differ from common polycrystalline metallic alloys, because their atoms do not assemble on a crystalline lattice, and as a result, they have unique physical, mechanical, and chemical properties. A number of BMGs have been found to ...
