Fabrication of biodegradable nano-sized β-TCP/Mg composite by a novel melt shearing technology

► β-TCP/Mg-3Zn-Ca composite was produced using a novel melt shear technology. ► Melt shear technology can improve the uniformity distribution of the β-TCP particles. ► Microstructure evolution during solidification process for composite was analysed. ► Mechanical properties of 1 wt.% β-TCP/Mg-3Zn-1Ca composites were tested. ► β-TCP/Mg-3Zn-1Ca composite is a candidate for biodegradable implant materials.
