Abstrakt: Mg-1.12Ca-0.84Zn-0.23Mn (at.%) alloy was reinforced by TiC nanoparticles. After extrusion ultra-fine grains of ∼0.4 μm were caused by Zener pinning effect of nano-sized particles including fine precipitated MgZn 2 phases, α-Mn particles and TiC nanoparticles. Yield strength of 423.6 MPa along with ultimate tensile strength of 436.8 MPa could meet biomedical application.
