What is claimed is: 1. A method of manufacturing a damped part comprising: providing an insert comprising a body portion comprising an inner edge and an outer edge; a plurality of tabs extending from at least one of the inner edge or outer edge of the body portion and wherein the tabs are tapered; positioning the insert in a mold such that the plurality of tabs at least assist in holding the insert in a desired position in the mold; and casting a material comprising a metal around the insert to form a part. 2. A method of manufacturing a damped part as set forth in claim 1 wherein the tabs have a triangular shape. 3. A method of manufacturing a damped part as set forth in claim 1 further comprising providing a coating over at least a portion of the body portion of the insert. 4. A method of manufacturing a damped part as set forth in claim 3 wherein the coating comprises at least one of silica, alumina, graphite with clay, silicon carbide, silicon nitride, cordierite (magnesium-iron-aluminum silicate), mullite (aluminum silicate), zirconia (zirconium oxide), phyllosilicates, other high-temperature-resistant particles, clay, Al2O3, SiO2, an organic binder, an inorganic binder, a lignosulfonate binder, a calcium lignosulfonate binder, cristobalite (SiO2), a fiber, a ceramic fiber, a mineral fiber, quartz, an epoxy resin, a phosphoric acid binding agent, calcium aluminates, sodium silicates, wood flour, non-refractory polymeric materials, ceramics, composites, wood, or a liquid dispersed mixture of alumina-silicate-based, organically bonded refractory mix. 5. A method of manufacturing a damped part as set forth in claim 1 wherein the insert comprises steel. 6. A method of manufacturing a damped part as set forth in claim 1 wherein the material comprises cast iron. 7. A method as set forth in claim 1 further comprising providing a layer comprising particles or fibers over at least a portion of the insert. 8. A method as set forth in claim 1 further comprising treating at least a portion of the insert so that the material comprising a metal does not wet the portion of the insert and bond thereto upon solidification. 9. A method as set forth in claim 1 wherein the body portion is annular.
