title: A new approach to the fabrication of porous magnesium with well-controlled 3D pore structure for orthopedic applications.
abstract: A new approach to the fabrication of porous magnesium by using the titanium wire space holder (TWSH) method has been developed. Since the entangled titanium wire structure is used as the space holder, the porous structure is pipe-like and interconnected, and the pore size is identical and equals to the diameter of the titanium wire. In particular, the pore size, porosity, and porous morphology of the porous magnesium can be exactly and individually controlled. When the porosity is in the range of 54.2-43.2%, the compressive yielding strength is in the range of 4.3-6.2 MPa, and the Young's modulus is in the range of 0.5-1.0 GPa.
