    摘要: Slurries containing tri-or polyvalent cations are used for investment casting and making molds as well as core coatings. These slurries are aqueous or alcohol-based containing a mineral component and a polyanionic binder, where at least one of the continuous phase or mineral component contains trivalent or polyvalent cations or cations that are converted into trivalent or polyvalent cations during use. The cationic component is selected from a group consisting of at least one of the metals iron or aluminum. The polyanionic component contains at least one of the group consisting of colloidal silica or one or more water-soluble organic polymers.

    摘要: The present invention relates to composite materials exhibiting passive domain-wall activated damping, methods for using passive domain-wall activated damping, and processes for producing materials that exhibit passive domain-wall activated damping. One typical embodiment uses a polymer matrix phase and a dispersed particulate phase that exhibits domain wall motion under an applied mechanical load. Materials that exhibit domain wall motion under an applied mechanical load include magnetostrictive, piezoelectric and electrostrictive materials. One specific embodiment used Terfenol-D as the damping phase, aligned by magnetization during curing in a polymer matrix. Other specific embodiments employed PZT-5H and PMN-PT as the damping phase.
