| Abstract | ||
| This study examines the effects of adding silicon carbide (SiC) on the mechanical properties of magnesium-tin (Mg-Sn-CaC) alloys produced via the powder metallurgy process. The objective is to evaluate how these carbides influence the hardness, strength, and overall mechanical performance of the Mg-Sn-CaC alloy. A constant ratio of Mg-Sn (93 wt.%, 2 wt.% Sn, and 5%wt. Ca2C) were mechanically mixed, with SiC added in varying proportions up to a maximum of 5 wt.%. The phase structure and microstructure were analyzed using X-ray diffraction (XRD) and scanning electron microscopy (SEM), XRD analysis identified solid solutions such as Mg₂Sn, Ca₂Sn, Si₂Mg₆Sn, and MgC phases. SEM analysis revealed a uniform distribution of Ca₂C and SiC within the Mg-Sn matrix. While density was determined using Archimedes' principle. Hardness and wear resistance were measured, where test specimens containing 3% SiC and 2% Ca₂C increased up to maximum then decreased. | ||
