dc.description.abstract | Titanium (Ti) and its alloys are used for biomedical applications because of their high
resistance to corrosion, good strength-to-weight ratio, and high fatigue resistance. However, a problem
that compromises the performance of the material is the mismatch between Young’s modulus of
Ti and the bone, which brings about stress shielding. One strategy that has been investigated to
reduce this di erence is the manufacture of Ti-based foams, using powder metallurgy (PM) methods,
such as the space-holder technique. However, in the uniaxial compaction, both non-uniform density
distribution and mechanical properties remain because of the compaction method. This work studies
the influence of compaction by adopting a floating-action die related to a single-action die (SAD),
on the density of green and sintered Ti foams with porosities around 50 vol.% characterized by optical
microscopy, ultrasound analysis, compression tests, and microhardness. The compaction process
employing a floating-action die generates Ti foams with a higher density up to 10% with more control
of the spacer particle added compared to the single-action die. Furthermore, compaction method has
no relevant e ect on microhardness and Young’s modulus, which allows getting better consolidated
samples with elastic modules similar to those of human bone. | es |
