“…Thus, the research in fabricating copper-based composite materials is ongoing, including Cu-Al 2 O 3 , Cu-Zr-Al 2 O 3 , Cu-TiO 2 , Cu-Si 3 N 4 , Cu-B 4 C, and Cu-SiC (10)(11)(12)(13)(14). Methods for fabricating these composite materials include casting, coprecipitation, internal oxidation, and powder metallurgy (15)(16)(17)(18)(19)(20).…”
