Cu-22Sn alloy fabrication by hot forging process is a Korean traditional forged high-tin bronze. The tin content is 22 percent, which is more than twice that of bronze ware traditionally used in China and the West. Copper and tin have a carbon solubility of several ppm at room temperature, making Cu-Sn-C alloys difficult to manufacture by conventional casting methods. Research on the production of carbon-added copper alloys has used a manufacturing method that is different from the conventional casting method. In this study, Cu-22Sn-xC alloy was fabricated by mechanical alloying and spark plasma sintering. The carbon solubility was confirmed in Cu-Sn alloy through mechanical alloying. The lattice parameter increased from A0 to C2, and then decreased from C4. The microstructural characteristics of sintered alloys were determined using X-ray diffraction and microscopic analysis. As a result of comparing the hardness of Cu-22Sn alloys manufactured by conventional rolling, casting, and forging and Cu-22Sn-xC alloy by sintered powder metallugy, B0 sintered alloy was the highest at about 110.9 HRB.}, type={Article}, title={Microstructure and Hardness of Cu-22Sn-xC Alloys Fabricated by Powder Metallurgy}, URL={http://journals.pan.pl/Content/126230/PDF/AMM-2023-1-10-Hee-Soo%20Kim.pdf}, doi={10.24425/amm.2023.141474}, keywords={Cu-Sn alloy, Nanocrystalline, Carbon solubility, Mechanical alloying}, }
