摘要： A method of processing BMGs in a non-ideal environment (such as air) to create a uniform and smooth surface is provided. By utilizing the contact-line movement and an engineered flow pattern during TPF the method is able to create complex BMG parts that exhibit uniform smooth appearance or even can be atomically smooth. In addition, to mending surface imperfections, this method also eliminates void formation inside the material, allows for the creation of precise patterns of homogeneous appearance, and forms improved mechanical locks between different materials and a BMG.

摘要： Bulk solidifying amorphous alloys exhibiting improved processing and mechanical properties and methods of forming these alloys are provided. The bulk solidifying amorphous alloys are composed to have high Poisson's ratio values. Exemplary Pt-based bulk solidifying amorphous alloys having such high Poisson's ratio values are also described. The Pt-based alloys are based on Pt—Ni—Co—Cu—P alloys, and the mechanical properties of one exemplary alloy having a composition of substantially Pt57.5Cu14.7Ni5.3P22.5 are also described.

摘要： Compositions for forming Au-based bulk-solidifying amorphous alloys are provided. The Au-based bulk-solidifying amorphous alloys of the current invention are based on ternary Au—Cu—Si alloys, and the extension of this ternary system to higher order alloys by the addition of one or more alloying elements. Additional substitute elements are also provided, which allow for the tailoring of the physical properties of the Au-base bulk-solidifying amorphous alloys of the current invention.

摘要： The formation of amorphous porous bodies and in particular to a method of manufacturing such bodies from amorphous particulate materials. The method allows for the control of the volume fraction as well as the spatial and size distribution of gas voids by control of the size distribution of the powder particulates. The method allows for the production of precursors of unlimited size, and because of the softened state of the amorphous metals used in the method possess visco-plastic properties, higher plastic deformations can be attained during consolidation as well as during expansion.
