Abstract
Official abstract text for this publication.
Described herein are methods of constructing a part using metallic glass alloys, layer by layer, as well as metallic glass-forming materials designed for use therewith. Metallic glass meshes, metallic glass actuators, three dimensional metallic glass thermal history sensors, and methods of their manufacture are also disclosed.
First claim
Opening claim text (preview).
What is claimed is: 1. A metallic glass actuator comprising: a first portion comprising a metallic glass, a second portion comprising a void structure; a third portion comprising the metallic glass of the first portion, wherein the third portion has a volume less than the volume of the first portion; and where the second portion is disposed between the first and third portions and wherein the metallic glass actuator is of unitary construction. 2. The metallic glass actuator of claim 1 wherein the void structure comprises at least 5% void by volume. 3. The metallic glass actuator of claim 2 wherein the void structure is created by metallic glass powder that is not compacted. 4. The metallic glass actuator of claim 1 wherein the first and third portions are composed of fused metallic glass powder. 5. The metallic glass actuator of claim 1 wherein the first and third portions comprise an electromechanical material which alters its shape under application of an electric field. 6. The metallic glass actuator of claim 1 wherein the first and third portions comprise a magnetostrictive material which alters its shape under application of a magnetic field. 7. The metallic glass actuator of claim 1 , wherein at least a portion of the metallic glass of the first portion surrounds the void structure.
