20160032436 | PROCESS FOR MAKING FINISHED OR SEMI-FINISHED ARTICLES OF SILVER ALLOY - A process for making a finished or semi-finished article of silver alloy, said process comprising the steps of providing a silver alloy containing silver in an amount of at least 77 wt %, copper and an amount of germanium that is preferably at least 0.5 wt % and is effective to reduce tarnishing and/or firestain, making or processing the finished or semi-finished article of the alloy by heating at least to an annealing temperature, gradually cooling the article; and reheating the article to effect precipitation hardening thereof. The avoidance of quenching reduces the risk of damage to the article. | 02-04-2016 |
20160067766 | 3D PRINTED INVESTMENT MOLDS FOR CASTING OF AMORPHOUS ALLOYS AND METHOD OF USING SAME - Described herein is a method of forming a 3D investment mold using a layer-by-layer construction (3D printing). The mold is configured for receipt of a molten alloy having a composition configured to form a bulk metallic glass (BMG) on cooling. The mold has a hollow interior between inner and outer walls. The hollow interior receives the molten alloy for molding it between the inner and outer walls of the mold. A method of casting using the 3D investment mold is also disclosed, which may include filling the mold with molten alloy, removing bubbles, quenching the molten alloy in the mold, and then removing the mold. | 03-10-2016 |
20160108484 | METHOD AND APPARATUS FOR SUPERCOOLING OF METAL/ALLOY MELTS AND FOR THE FORMATION OF AMORPHOUS METALS THEREFROM - A method and apparatus is described for creation of amorphous metals using electromagnetic supercooling of a metal/alloy without the utilization of rapid quenching nor immaculate process environments. By exposing the cooling melt to electric currents, either induced by an alternating magnetic field or supplied directly, crystallization is suppressed and the melt can reach significant levels of supercooling. With sufficient current densities in the melt the supercooling can extend all the way into the glass transition range for certain materials at which point an amorphous metal/alloy is created. | 04-21-2016 |
