Metallic glasses with crystalline dispersions formed by electric currents |
August 15, 2006 |
| Metallic glasses of superior mechanical and magnetic properties are manufactured by annealing the glasses under the influence of an electric current to convert the glass to a composite that includes crystallites, preferably nanocrystallites, dispersed through an amorphous matrix. |

One-step synthesis and consolidation of nanophase materials |
March 13, 2001 |
| Solid reaction products with a dense nanocrystalline structure are formed from reactant particles with diameters in the nano-scale range by compacting the particles into a green body, then passing an electric current through the body causing Joule heating sufficient to initiate the r |

Centrifugal synthesis and processing of functionally graded materials |
October 24, 2000 |
| A method through which we can synthesize Functionally Graded Materials (FGM). Such materials are made so that their composition changes gradually from one point to another, such as in the example of gradient index (GRIN) optical components. A novel aspect of our method is the imposition |
