| 20090014096 | HIGH CORROSION RESISTANT Zr-Ti BASED METALLIC GLASSES - Bulk solidifying amorphous alloys (BMGs) having improved corrosion resistance properties; and more particularly a sub-set of Zr—Ti-based BMGs having improved corrosion resistance properties are provided. The BMG compositions are formed by carefully controlling the concentration of, or removing altogether, highly electronegative elements, such as Ni and Cu from Zr—Ti-based bulk solidifying amorphous alloys thereby producing BMG materials with corrosion resistance properties that far exceed those of current commercially available BMGs and most conventional alloys. The elimination of these electronegative materials also opens the possibility of new uses for BMGs, including in biological applications. | 01-15-2009 |
| 20090053476 | MULTILAYERED CELLULAR METALLIC GLASS STRUCTURES AND METHODS OF PREPARING THE SAME - Multi-layered cellular metallic glass structures and methods of preparing the same are provided. In one embodiment, the cellular metallic glass structure includes at least one patterned metallic glass sheet and at least one additional sheet. The at least one patterned metallic glass sheet may include multiple sheets connected together to form a group of sheets, and the structure may include a group of sheets sandwiched between two outer sheets. The patterned metallic glass sheets may be patterned by thermoplastically forming two- and/or three-dimensional patterns in the metallic glass sheets. The metallic glass cellular structures are useful in a wide variety of applications, including but not limited to blast protection applications, energy absorption applications, structural support applications, biomedical implant applications, heat exchanger applications, thermal management applications, electrical shielding applications, magnetic shielding applications, and debris and radiation shielding for aerospace and outer space applications. | 02-26-2009 |
| 20090162629 | NI AND CU FREE PD-BASED METALLIC GLASSES - The invention is directed to Pd-based metallic glass alloys useful in biomedical applications having no Ni or Cu. Exemplary metallic glass alloys are represented by A | 06-25-2009 |
| 20090236017 | FORMING OF METALLIC GLASS BY RAPID CAPACITOR DISCHARGE - An apparatus and method of uniformly heating, rheologically softening, and thermoplastically forming metallic glasses rapidly into a net shape using a rapid capacitor discharge forming (RCDF) tool are provided. The RCDF method utilizes the discharge of electrical energy stored in a capacitor to uniformly and rapidly heat a sample or charge of metallic glass alloy to a predetermined “process temperature” between the glass transition temperature of the amorphous material and the equilibrium melting point of the alloy in a time scale of several milliseconds or less. Once the sample is uniformly heated such that the entire sample block has a sufficiently low process viscosity it may be shaped into high quality amorphous bulk articles via any number of techniques including, for example, injection molding, dynamic forging, stamp forging, and blow molding in a time frame of less than 1 second. | 09-24-2009 |
| 20100230012 | AMORPHOUS PLATINUM-RICH ALLOYS - According to embodiments of the present invention, an amorphous alloy includes at least Pt, P, Si and B as alloying elements, and has a Pt weight fraction of about 0.925 or greater. In some embodiments, the Pt weight fraction is about 0.950 or greater. | 09-16-2010 |
| 20100300148 | TOUGH IRON-BASED BULK METALLIC GLASS ALLOYS - A family of iron-based, phosphor-containing bulk metallic glasses having excellent processibility and toughness, methods for forming such alloys, and processes for manufacturing articles therefrom are provided. The inventive iron-based alloy is based on the observation that by very tightly controlling the composition of the metalloid moiety of the Fe-based, P-containing bulk metallic glass alloys it is possible to obtain highly processable alloys with surprisingly low shear modulus and high toughness. | 12-02-2010 |
