Porous Ti-based alloys enable various orthopedic applications but "they are often hindered by structure-derived stress concentration failure, low strength, poor plasticity or uncertain biosecurity caused by the extra space holder. Here, we present a radial gradient porous composite with structure-derived favorable pore characteristics achieved by designing a hierarchical porous architecture composed of a central Ti-Ag micro-pore core and an outer interconnected spherical Ti porous layer with 49% porosity as well as 105 mu m average pore size. Simultaneously, the composite exhibits an exceptionally low elastic modulus (16.8 GPa) and high compressive strength (1248 MPa), together with an excellent plastic deformation ability (over 40%) owning to the eutectoid transformation: beta-Ti -> alpha-Ti+Ti2Ag and the continuous gradient structure. An combination of pore characteristics, large plasticity, low elastic modulus, high strength and favorable osteoblast affinity implies the Ti-Ag/Ti composite is a good, potential candidate for orthopedic surgery and other medical applications.
