Abstract
In the process of powder metallurgy, titanium powder is compressed into a green body and sintered into a net shape. Investigations were done into how the processing factors affected the physical, microstructural, and mechanical qualities. In the current study, titanium foam with adjustable porosity was created utilizing a newly invented powder metallurgy technique called the space-holder approach. The stress-shielding effect, that encourages bone resorption around implants, is primarily caused by the high Young's modulus of titanium relative to the surrounding bone. Growing scientific and technological interest has been paid for to the development of titanium foam for implants that have a low Young's modulus. This study's objective is to assess the commercial viability, industrial applicability, and potential technology transfer of several powder metallurgy methods. Under various strain rates, titanium foam of varying relative densities was analyzed for their compressive deformation behaviors. Foam's plateau stress, Young's modulus, and energy absorption all increase with increasing relative density, as predicted by power law correlations. Nonetheless, densification strain increases proportionally with increasing relative density. The strain rate compassion and the strain rate sensitivity parameter of these foams were also studied. This research not only traces the origins of the mechanical properties of titanium foams, but also demonstrates the substantial practical value of the new method of measuring porosity.
