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 105µm average pore size. Simultaneously, the composite exhibits an exceptionally low elastic modulus (16.8GPa) and high compressive strength (1248MPa), together with an excellent plastic deformation ability (over 40%) owning to the eutectoid transformation: β-Ti→α-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.
