METHODS FOR IMPARTING COMPRESSIVE STRESS ON METALLIC GLASS PARTS

摘要

Described herein are methods of constructing a part using metallic glass-forming alloys, layer by layer, as well as bulk metallic glass-forming materials designed for use therewith. In certain embodiments, a layer of metallic glass-forming alloy powder, wire, or a sheet of metallic glass material is deposited to selected positions and then fused to a layer below by suitable methods such as laser heating or electron beam heating. The deposition and fusing are then repeated as need to construct the part, layer by layer. One or more sections or layers of material that is not a metallic glass can be included as needed to form composite parts.
