A method of forming and assembling at least two parts together that may be metal, ceramic, or a combination of metal and ceramic parts. Such parts may have different CTE. Individual parts that are formed and sintered from particles leave a network of interconnecting porosity in each sintered part. The separate parts are assembled together and then a fill material is infiltrated into the assembled parts using a method such as capillary action, gravity, and/or pressure. The assembly is then cured to yield a bonded and fully or near-fully dense part that has the desired physical and mechanical properties for the part's intended purpose. Structural strength may be added to the parts by the inclusion of fibrous materials.
