<p>A sheet is prepared by mixing a mass of metallic powders with a temporary thermoplastic binder to form an injection-moldable mixture, thereafter injection molding the injection-moldable mixture to form a sheet precursor. The sheet precursor is consolidated to a relative density of substantially 100 percent to form the sheet, and thereafter heat treated. The final sheet is preferably a nickel-base superalloy having more than about 30 volume percent of gamma prime phase, or an intermetallic such as a titanium aluminide.</p> |
