Irvin C. Huseby has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: A ceramic article suitable for use in the casting of advanced superalloy materials has a structure of a predetermined porosity content and consists of either 3Y.sub.2 O.sub.3 .multidot. 5Al.sub.2 O.sub.3, Y.sub.2 O.sub.3 .multidot. Al.sub.2 O.sub.3 or 2Y.sub.2 O.sub.3 .multidot. Al.sub.2 O.sub.3 or two-phase mixtures of these single-phase materials.
Abstract: A ceramic suitable for use in the casting of advanced superalloy materials has a structure including a predetermined porosity content and a material microstructure characterized by a high density of microcracks.
Abstract: The crushability of a ceramic article suitable for use in the casting and directional solidification of advanced superalloy materials is enhanced by utilizing a two-phase mixture of material and inducing microcracks in the material. The crushability is further enhanced by forming the article to include a predetermined porosity content.
Abstract: Cores made of either Y.sub.2 O.sub.3, Y.sub.3 Al.sub.5 O.sub.12, LaAlO.sub.3, MgAl.sub.2 O.sub.4 or Al.sub.2 O.sub.3 are removed from castings of advanced superalloy materials by immersion in a molten salt bath of either Li.sub.3 AlF.sub.6 or a mixture of CaF.sub.2 -- NaF.

Abstract: A magnesium-boron composite is made by mechanically mixing magnesium powders with boron powders. An alternative embodiment includes mixing a small amount of lithium powder with the magnesium boron composite to improve the ductility. The mixed powders are processed by cold pressing, hot pressing, sintering, extruding, rolling and re-extruding.
